What Factor Is Most Important In Determining Whether Water Is A Solid Liquid Or Gas?

Temperature is the most important factor in determining the state of basically any molecular system.

What determines if water is in a solid liquid or gas state?

At low temperatures (below 0°C) it is a solid. When at “normal” temperatures (between 0°C and 100°C) it is a liquid. While at temperatures above 100°C water is a gas (steam). The state the water is in depends upon the temperature.

What is the important factor which decide the state of matter?

Answer: The amount of energy in molecules of matter determines the state of matter. Matter can exist in one of several different states including a gas liquid or solid state. … A gas is a state of matter in which atoms or molecules have enough energy to move freely.

What makes water liquid in the state?

At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade) water is found in a liquid state. This is because of the tiny weak hydrogen bonds which in their billions hold water molecules together for small fractions of a second. Water molecules are constantly on the move.

What makes water change from solid to a liquid to a gas?

When solid ice gains heat it changes state from solid ice to liquid water in a process called melting. Ice cubes in a cold drink for example gradually melt. … When water absorbs enough heat it becomes a gas (water vapor). This process is called evaporation.

What are the three factor that determine the state of matter?

Kinetic energy of atoms ions or molecules of substance.
Intermolecular force of attraction.
Intermolecular spaces between atoms.

What are the two factors that decide the state of a matter explain?

Answer:Temperature pressure and intermolecular space.

On what factors do the stability of the state of matter depends upon?

Which state a substance is in depends partly on temperature and air pressure. For example at the air pressure found at sea level water exists as a liquid at temperatures between 0oC and 100oC. Above 100oC water exists as a gas (water vapor). Below 0oC water exists as a solid (ice).

Why is water considered as a liquid and not a solid or a gas?

Water is considered as a liquid because the molecular weight of it. The molecules in water are not closely packed as in a solid. But not as far away like in gases.

Can water go from solid to gas?

Comparison of phase diagrams of carbon dioxide (red) and water (blue) showing the carbon dioxide sublimation point (middle-left) at 1 atmosphere. As dry ice is heated it crosses this point along the bold horizontal line from the solid phase directly into the gaseous phase.

How is water different when it is liquid form compared to solid?

Unlike most other substances water’s solid form (ice) is less dense than its liquid form as a result of the nature of its hexagonal packing within its crystalline structure. This lattice contains more space than when the molecules are in the liquid state. … Liquid water is most dense at 4 degrees Celsius.

In which part of the water cycle does water change from a liquid to a gas?

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.

What is the change of state of water from gas to liquid?

Condensation

Condensation is the change of state from a gas to a liquid.

How does water become gas?

Evaporation happens when a liquid turns into a gas. … When liquid water reaches a low enough temperature it freezes and becomes a solid—ice. When solid water is exposed to enough heat it will melt and return to a liquid. As that liquid water is further heated it evaporates and becomes a gas—water vapor.

What are the factors that decide the state and physical properties of matter?

Different factors affecting physical and chemical properties of matter are the boiling point melting point solubility density reactivity and temperature.

What are the factor responsible for the existence of matter in different states?

The two factors on which the existence of matter in a particular state depend are temperature and pressure.

What are the common factors of matter?

The common things among the three states of matter are:

They are made up of small tiny particles.
They have a particular mass and can occupy space.
These three states have volume in it.
The atoms of these three states have force of attractions between them.

What two factors that we discussed determine the physical state of a substance?

temperature pressure & purity are the factors that determine the state of a substance.

What does the state of matter depend on?

A substance’s state of matter — solid liquid gas or plasma — depends on how its molecules move and maintain their volume and shape.

On what factors do the properties of a substance depends?

Explanation: Extensive properties such as mass and volume depend on the amount of matter being measured. Intensive properties such as density and color do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity.

Which two factors are needed to determine the number of atoms or molecules that are present in a substance?

Determine the mass of the substance and its molar mass. Divide the given mass by its molar mass to get moles then multiply times 6.022×1023molecules1mol .

Why is water considered matter?

Answer: Matter can change from one state to another when physical conditions change when energy such as heat is added or removed a substance can change from a solid to a liquid or from a liquid to a gas. … Water is unique because the properties of water allow it to exist in all three states of matter!

What is water in its solid state called?

Ice is the solid state of water a normally liquid substance that freezes to the solid state at temperatures of 0 °C (32 °F) or lower and expands to the gaseous state at temperatures of 100 °C (212 °F) or higher.

Why is water considered as a liquid Class 9?

Ans. (a) Water at room temperature is a liquid because its freezing point is 0 °C and boiling point is 100 °C.

What temperature will water change from a solid to a liquid?

32° Fahrenheit

The solid begins to go from a solid state to a liquid state — a process called melting. The temperature at which melting occurs is the melting point (mp) of the substance. The melting point for ice is 32° Fahrenheit or 0° Celsius.

What point has water reached when it turns from a liquid to a solid?

Water turns to ice at 32ºF (0ºC). This is known as its freezing point.

Under what conditions do solid liquid and gases change their state?

We can change a solid into a liquid or gas by changing its temperature. This is known as changing its state. Water is a liquid at room temperature but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapor) if it is heated up.

How is water different from most states of matter?

Water is unique because the properties of water allow it to exist in all three states of matter! Water is usually a liquid but when it reaches to 32° Fahrenheit (F) it freezes into ice. (Ice is the solid state of water.) … (Steam is the gas state of water and is also called water vapor.)

Why water is different from most liquids with respect to its density in the solid and liquid states?

Explanation: When water freezes the molecules do not stack into a close-packed structure. … While water is unusual it is not unique. Elemental silicon forms a relatively open tetrahedral structure when solid and as with water the extra volume in this structure makes solid silicon less dense than the liquid.

What is the relationship between the state of matter of water gas liquid solid and the motion of the water molecules?

On the molecular level when in solid form (liquid water) particles have less energy/movement but the particles have more energy and are more spread out in gas form (water vapor). When water is in its solid-state (ice) the water molecules are packed close together preventing it from changing shape.

How does water molecules change in each step of the water cycle?

There are four main stages in the water cycle. They are evaporation condensation precipitation and collection. … Condensation: This is when water vapour in the air cools down and turns back into liquid water. Precipitation: This is when water (in the form of rain snow hail or sleet) falls from clouds in the sky.

During which process of the water cycle does water change?

Evaporation is the process by which water changes from a liquid to a gas or vapor.

What affects the water cycle?

Put simply water evaporates from the land and sea which eventually returns to Earth as rain and snow. Climate change intensifies this cycle because as air temperatures increase more water evaporates into the air. … Still more evaporation from the soil and an increased risk of drought.

What are the three states of water how can water be changed from one state to the other?

If ice (solid) is heated it changes to water (liquid). This change is called melting. Water (liquid) can change to water vapour (gas). This is called evaporation.
