What is the scientific term for air pressure?

Scientific definitions for atmospheric pressure

atmospheric pressure. [ ăt′mə-sfîr′ĭk ] The pressure at any location on the Earth caused by the weight of the column of air above it. At sea level atmospheric pressure has an average value of one atmosphere and gradually decreases as altitude increases.

What is air pressure in your own words?

Describe air pressure in your own words. It is the pressure exerted on Earth’s surface due to the weight of the overlying air molecules. … The aneroid barometer has a partly evacuated vacuum chamber that compresses as the pressure increases.

What is the term air pressure?

The air around you has weight and it presses against everything it touches. That pressure is called atmospheric pressure or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.

What do you mean by air pressure?

The definition of air pressure is the force exerted onto a surface by the weight of the air. An example of air pressure is the average sea-level air pressure of 101.325 kPA. noun.

What is pressure short answer?

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area.

What is the low pressure area called?

Low Pressure Centers: also known as cyclones. A surface low pressure center is where the pressure has been measured to be the lowest relative to its surroundings. That means moving any horizontal direction away from the Low will result in increasing pressure.

What does outside pressure mean?

there is more room on the outside than on the inside q. This expression means it is better to let one’s emotions out rather than bottled up inside. It is also often said when someone has gas.

What is the origin of air pressure?

Atmospheric pressure is caused by the gravitational attraction of the planet on the atmospheric gases above the surface and is a function of the mass of the planet the radius of the surface and the amount and composition of the gases and their vertical distribution in the atmosphere.

How do you explain air pressure to a child?

Air pressure is a measure of the weight of air above us in the atmosphere. Air pressure changes with the weather. High pressure happens when cold air pushes down usually bringing fine weather. Low pressure happens when warm air rises up to make clouds and rain.

What causes atmospheric pressure?

Air pressure is caused by the weight of the air molecules above. Even tiny air molecules have some weight and the huge numbers of air molecules that make up the layers of our atmosphere collectively have a great deal of weight which presses down on whatever is below.

What is the opposite of air pressure?

The term air pressure typically refers to the fluid pressure of air. There are no categorical antonyms for this word. However one could loosely use vacuum as an antonym.

Is air pressure and atmospheric pressure same?

Air pressure is the pressure exerted by the air around us while Atmospheric pressure is the pressure exerted by the atmosphere on the earth. Air pressure is measured by tore gauge while atmospheric pressure is measured using mercury barometer.

How can you observe air pressure?

How do you explain air pressure in water?

Air presses down equally on the water in the bottle and in the straw when there is no balloon present ( or the balloon is pegged ) but when the peg is removed air from the balloon increases the air pressure in the bottle which pushes down on the water forcing it through the straw.

What do you mean by the term pressure explain by giving examples?

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). While you sip the beverage you’re actually applying ‘Pressure’. …

How many types of pressure are there?

There are two basic pressure types: absolute and gauge distinguished by what pressure they are compared to which is called the reference pressure.

What is thermodynamic pressure?

Thermodynamic pressure represent the total energy of the fluid represented in terms of pressure head. When the fluid is static both are same as there is no additional source of energy in fluid. But when in motion the liquid also has kinetic energy which is in terms of velocity.

What is low pressure air?

A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure and the air rises in the atmosphere where they meet. As the air rises the water vapor within it condenses forming clouds and often precipitation. … Winds blow away from high pressure.

What is another name for a high pressure center?

High Pressure Centers: also known as anticyclones. A high pressure center is where the pressure has been measured to be the highest relative to its surroundings. That means moving in any direction away from the “High” will result in a decrease in pressure.

What is a high pressure system called?

High-pressure systems are alternatively referred to as anticyclones. On English-language weather maps high-pressure centers are identified by the letter H in English within the isobar with the highest pressure value.

What is barometric pressure in weather?

Barometric pressure is the weight of the overlying air pressing down on the earth. It is also known as air pressure. Low barometric pressure means the overlying air is rising whereas high pressure means the overlying air is sinking.

What is meant by atmospheric air?

Atmospheric air is the air which is prevailing under atmospheric conditions. Atmospheric conditions are different for different locations and patterns of wind. Atmospheric air is corrosive in areas where corrosive pollutants are present or emitted.

What is considered high air pressure?

What is high atmospheric pressure? Atmospheric pressure is usually measured in inches of mercury (inHg or Hg). High air pressure is considered to be greater than 31 inches or can be less than 29 inches. Normal pressure at sea level is 29.92 inches.

What is meant by absolute pressure?

The definition of absolute pressure is the pressure of having no matter inside a space or a perfect vacuum. Measurements taken in absolute pressure use this absolute zero as their reference point. The best example of an absolute referenced pressure is the measurement of barometric pressure.

What is air pressure easy language?

Atmospheric pressure is a force in an area pushed against a surface by the weight of the atmosphere of Earth a layer of air. … This is because high places do not have as much air above them pushing down. Barometers can be used to measure atmospheric pressure. There is the same atmospheric pressure from all directions.

What are two different units for atmospheric pressure?

Atmospheric pressure is expressed in several different systems of units: millimetres (or inches) of mercury pounds per square inch (psi) dynes per square centimetre millibars (mb) standard atmospheres or kilopascals.
