## What is the similarities between conduction and convection?

Both conduction and convection require some form of direct contact and the heat travels from molecule to molecule. Perfect vacuum means there are no molecules but convection and conduction need some medium to transfer heat. If there are no molecules heat by convection and conduction cannot be transferred.

## How convection and conduction is inter related?

Answer: The transfer of heat is through heated solid substance in conduction whereas in convection the heat energy is transmitted by way of intermediate medium.

## What does conduction and radiation have in common?

Both conduction & radiation involve heat transfer “which is similarity” . However radiation can go through empty space but conduction will have fast moving particles of the warmer object sending heat to slow moving particles on the cooler object upon physical contact between the 2 objects.

## How do conduction and convection work together?

The direct transfer of heat from one substance to another substance that it is touching is called conduction. … The transfer of heat by the move ment of a fluid is called convection. Heating the Troposphere Radiation conduction and. convection work together to heat the troposphere.

## How are conduction convection and radiation alike and different?

In conduction heat transfer takes place between objects by direct contact. In convection the heat transfer takes within the fluid. In radiation heat transfer occurs through electromagnetic waves without involving particles. … The heat transfer occurs through a heated solid object.

## What is the similarity of convection and radiation?

3 Similarities between conduction convection and radiation are given below: All of the three are involved in thermal energy. They all occur on oven and stove top. They all involve heat.

## What are the two factors that affect conduction on the earth’s surface?

Thanks to physics we know that conduction is affected by temperature difference the area of conduction the distance the heat must travel and the amount of time that passes.

## How does convection affect the formation of mountains and the temperature in the surface?

Convection currents carry heat from the lower mantle and core to the lithosphere. … As tectonic plates slowly move away from each other heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises often forming a mountain or elevated area of the seafloor.

## What process by which heat is directly transmitted?

Conduction is the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions without movement of the material.

## What is conduction and convection and radiation?

Conduction is the process of transfer of heat through direct contact. Convection is a mode of heat transfer that involves the movement of molecules. Radiation is a mode of heat transfer that occurs through electromagnetic waves.

## What is conduction convection and radiation examples?

Conduction: Heat transfers into your hands as you hold a hot cup of coffee. Convection: Heat transfers as the barista “steams” cold milk to make hot cocoa. Radiation: Reheating a cold cup of coffee in a microwave oven.

## How can heat be transferred through radiation?

Radiation is the transfer of heat by means of electromagnetic waves. … The transfer of heat by radiation involves the carrying of energy from an origin to the space surrounding it. The energy is carried by electromagnetic waves and does not involve the movement or the interaction of matter.

## What is convection and conduction?

Conduction: This is a flow of heat by direct contact. Heat travels from a warmer object toward a colder object. … Convection: This is a transfer of heat by mixing a fluid. Convection occurs within liquids and gases. Examples include boiling water and when warm water mixes with cold water.

## How convection and conduction affect the temperature in our atmosphere?

Conduction radiation and convection all play a role in moving heat between Earth’s surface and the atmosphere. … Conduction directly affects air temperature only a few centimeters into the atmosphere. During the day sunlight heats the ground which in turn heats the air directly above it via conduction.

## How do conduction and convection work together to transfer heat upward?

How do conduction and convection work together to transfer heat upward? Conduction transfers energy near the surface both downward into the surface and upward to the laminar boundary layer. Convection transfers energy through the atmosphere through free and/or forced convection processes.

## What’s the difference between conduction and convection current?

An example of a convection current is a cloud bearing free electrons that moves through the atmosphere driven by wind. Conduction current consists of charged particles moving in response to the electric field and not merely being carried by motion of the surrounding material.

## What is the difference between conduction and convection name one medium in each case where it is the primary mode of heat transfer?

➡️Conduction: The transfer of heat in the direction of heat flow from one molecule to another without the actual displacement of molecules from their mean position is called conduction. … ➡️The transfer of heat from higher temperature to lower temperature with the actual movement of molecules is called convection.

## What is the difference between diffusion and radiation heat transfer?

Diffusion heat transfer is due to random molecular motion. Neighboring molecules move randomly and transfer energy between one another – however there is no bulk motion. Radiation heat transfer on the other hand is the transport of heat energy by electromagnetic waves. All bodies emit thermal radiation.

## What is conduction and radiation?

Conduction can be considered as the flow of heat along a body or between one body and another. The heat flows from the hotter region to the cooler until the temperature is uniform. Radiation is the transfer of heat in wave form.

## How convection in Earth’s interior and conduction in the surface affect the?

The temperature in our atmosphere is influenced by conduction radiation and convection from the earth’s interior and surface. … Conduction has a direct effect on air temperature only a few millimeters into the atmosphere. During the day sunlight heats the soil which then heats the air directly above it by conduction.

## Why does convection only occur in liquids and gases?

Convection only happens with fluids materials that can flow. Liquids can flow (think of water) and gases can flow (think of wind). Solids are stuck in place so they can’t flow and since they can’t flow there is no convection. The way heat transfers through solids is conduction.

## How does convection affect Earth’s interior temperature?

Convection works by areas of a liquid or gas heating or cooling greater than their surroundings causing differences in temperature. These temperature differences then cause the areas to move as the hotter less dense areas rise and the cooler more dense areas sink.

## How does convection current in the mantle affect the landmass on the surface of the earth?

Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth’s mantle. … Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth’s crust.

## How do mid ocean ridge and trenches form during convection currents?

These plates are moving constantly but are moving very very slowly. They move because of something called convection currents. Convection currents push these plates together and apart. … When two oceanic plates are pushed away from each other magma rises to the surface between the plates and creates a ridge.

## How does convection current affect plate tectonics?

The convection currents move the plates. Where convection currents diverge near the Earth’s crust plates move apart. Where convection currents converge plates move towards each other. The movement of the plates and the activity inside the Earth is called plate tectonics .

## What kind of heat transfer occurs mostly on the earth?

Most of the heat transfer that is taking place on the earth is by radiation.

## What process by which heat is directly transmitted through a substance when there is difference of temperature?

what is convection? the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions without movement of the material.

## Which method of heat transfer transmits heat from the sun to the road?

Radiation is the method of heat transfer by which the sun warms the earth. Light rays travel from the sun through space to the earth. The other methods need a medium to travel through. conduction.
