## When hot and cold air meet the hot air rises to the top which process causes the hot air to rise a conduction B radiation C convection d induction?

convection Explanation: The process by which hot and cold air are transferred in the atmosphere is convection. The hot air is less dense and rises; it then cools, condenses and becomes more dense and falls back down. 3) When gasoline is burned in a car engine, ________ energy is converted into _________ energy.

## What process causes hot air rise?

Convection. When a fluid such as air or water touches a hot object, it can heat up and then move in bulk as a fluid, thereby carrying the heat quickly to new locations. Hot air rising is a common example of heat convection.

## What do you call of the process where warm air rises and cold air sink?

Convection is defined as the circulation of fluids (liquids or gases), either natural or forced. Hot or cold fluids can add or remove heat. Natural convection is caused by density differences. Hot air rises because it is less dense than cold air, so air will rise above a heater and sink near a cold window.

## Why Does hot air rise up and cold air come down?

Hot air rises because gases expand as they heat up. When air heats up and expands, its density also decreases. The warmer, less dense air effectively floats on top of the colder, denser air below it. This creates a buoyant force that causes the warmer air to rise.

## What is conduction and convection?

Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas.

## What is the difference between conduction and convection?

In conduction, heat transfer occurs 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 takes place due to the difference in temperature.

## What type of heat transfer takes place of the warm air rises?

Convection Convection occurs when heat is carried away from your body via moving air. If the surrounding air is cooler than your skin, the air will absorb your heat and rise. As the warmed air rises around you, cooler air moves in to take its place and absorb more of your warmth.

## Why does heat rise in convection?

So, though colloquially it can be said that in the case of convection, heat rises, what really happens is that the air is heated by conduction. The exchange of heat energy causes the air molecules to move faster, which causes them to move apart from one another and reduce the density.

## What happens when hot and cold air meet?

When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses. This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain.

## What type of front is formed when cool air cold air and warm air meet?

occluded front This is known as an occluded front. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together. Occluded fronts usually form around areas of low atmospheric pressure.

## How does heat transfer occur through convection?

Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises (see Ideal Gas Law).

## When warm air rises cold air will quizlet?

Warm air rises and cold air sinks because of the uneven heating on the earth. How is wind formed?

## What is convection process of heat transfer?

Convection. Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water.

## What is the process of convection?

Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid.

## What is heating by convection?

Heat convection is the transfer of thermal energy by the physical movement of fluid (liquid, gas, or plasma) from one location to another. Heat convection is often the primary mode of energy transfer in liquids and gases. Along with conduction and radiation, convection is one of three basic methods of heat transfer.

## How is heat transferred through convection?

Convection. Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water.

## What is the process of conduction?

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart.

## What is the convection process?

Convection is the process by which heat is transferred from a solid surface to a nonsolid, such as air or water. The convection process involves the motion of the fluid relative to the solid surface and the processes by which heat is transferred across the interface.

## What happens during the process of convection?

convection, process by which heat is transferred by movement of a heated fluid such as air or water. Natural convection results from the tendency of most fluids to expand when heated—i.e., to become less dense and to rise as a result of the increased buoyancy.

## What happens when cold and warm fronts meet?

An occluded front forms when a cold front reaches a warm front, forcing all the warm air to rise to higher altitudes and the cold air is stratified near the ground.

## What type of front is formed when cool air and warm air meet?

This is known as an occluded front. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together. Occluded fronts usually form around areas of low atmospheric pressure.

## What is it called when hot and cold air meet?

When two different air masses come into contact, they don't mix. They push against each other along a line called a front. When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses. This type of front is called a warm front.

## What kind of heat transfer is warm air rising?

Convection Convection occurs when heat is carried away from your body via moving air. If the surrounding air is cooler than your skin, the air will absorb your heat and rise. As the warmed air rises around you, cooler air moves in to take its place and absorb more of your warmth.

## Why does warm air rise and cold air sink quizlet?

Why does warm air rise and cold air sink? Warm air rises and cold air sinks because of the uneven heating on the earth. How is wind formed? Wind is formed by the uneven heating of the earth, causing the warm air to rise and the cold air to sink.

## What is heat transfer through conduction?

Conduction heat transfer is the transfer of heat through matter (i.e., solids, liquids, or gases) without bulk motion of the matter. In another ward, conduction is the transfer of energy from the more energetic to less energetic particles of a substance due to interaction between the particles.

## What is conduction energy transfer?

Conduction is the transfer of energy from one molecule to another by direct contact. This transfer occurs when molecules hit against each other, similar to a game of pool where one moving ball strikes another, causing the second to move.

## What is process of conduction?

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart.
