Adding heat to an object is essentially adding energy. When energy is added to a gas, the individual molecules of the gas begin to move faster and bounce off of each other and the container the gas is in. The more energy added, the more they bounce and the faster they move. This causes the gas to expand, which increases the pressure inside the vessel.

∙ 10y agoThrough Adiabatic processes The first law of thermodynamics with Q=0 shows that
all the change in internal energy is in the form of work done. The ratio of the specific
heats γ = CP/CV is a factor in determining the speed of sound in a gas and other
adiabatic processes as well as this application to heat. This ratio γ = 1.66 for an
ideal monoatomic gas and γ = 1.4 for air, which is predominantly a diatomic gas.

Answer #2:
Answer #1 is elegant, as well as true, informative, and excellent.
But my kids want something they can feel. The way I explain it to them is:
You have to spend energy (do work) on the air in order to compress it ... either
pushing and squeezing more air into the same bottle, or pushing and squeezing the
same air into a smaller bottle. All that energy has to go somewhere. It becomes
heat energy in the gas. When you let the gas push on something movable, the
pressure will do work: It'll move the thing it's pushing on. The energy to do that
work comes out of the compressed air, it gets less compressed, and it gets cold.

When a volume of air is compressed what happens to its temperature?
Obviously the temperature of air will increase. Because when you compress the air you are doing some work on the air which in turn is converted into heat and thus increase the temperature of compressed air
What happens when air is compressed?
When air particles are compressed, the density is increased. There is more pressure within a region or within a container. There are more molecules in a given volume, and this can cause the air to heat up. - The pressure of the air increases, as does its temperature, as its volume decreases.
When a volume of air is compressed its temperature does it increase or decrease or neither?
There is a thing called the "heat of compression" which causes all compressed substances to increase in temperature.
What is the study of compressed air?
compressed air science
What is the purpose of a compressed air dryer?
A compressed air dryer is used to remove water vapor from compressed air. Compressed air dryers are used mostly in commercial and industrial facilities.
Why is after cooler is used in diesel engines?
An time air is compressed it heats up,cooler air makes more power. An intercooler/aftercooler reduces the heat build up.
Why pump can't use for compressed air?
Pump cant use compressed air because its a heat exchange process where mostly burnt fuel is converted as a source of energy . Compressed air is best in compressor engines .
What are the properties of compressed air.can it hold more heat when air passed through a heat exchanger?
Yes
When a volume of air is compressed what happens to its temperature?
Obviously the temperature of air will increase. Because when you compress the air you are doing some work on the air which in turn is converted into heat and thus increase the temperature of compressed air
What are everyday examples of adiabatic process?
Air is made up of a mixture of gases that is subject to adiabatic heating when it is compressed and adiabatic cooling when it is expanded.
Explain the tire becomes warm when air is being pumped into it?
when air is compressed it heats up because the uncompressed air contains heat. Heat is a form of energy that's all around us even in the coldest winter. Cold is void of heat, cold is caused by the lack of heat energy. That being said, when you compress air containing heat, the heat is also compressed. This causes the tire and the air inside to be warmer that the surrounding area till the heat is dissipated to the surrounding area. The tire and it's air inside becomes the same temperature as the surrounding space. Just remember, heat is a form of energy.
What does compressed and zipped mean on a computer?
Compressed: The compressed air in bottle which can be bought at Home Depot.Zipped: When you zip up a zipper (i.e. "I zipped up my jacket.")
What happens when air is compressed?
When air particles are compressed, the density is increased. There is more pressure within a region or within a container. There are more molecules in a given volume, and this can cause the air to heat up. - The pressure of the air increases, as does its temperature, as its volume decreases.
Why do clouds disappear with high air pressure?
In a high pressure system air sinks and is compressed. As the air is compressed it heats up, which can cause clouds to evaporate.
Why do space vehicles heat up when they enter the earth's atmosphere?
The Space vehicles heat up when they enter the earth's atmosphere because the tendency of the air is to compress quickly when the space vehicle hits the atmosphere. When the gasses compressed the temperature also rises which causes the heat.
In a diesel engine the air fuel mixture is ignited by?
It is ignited by compression. The air fuel mixture is compressed by the piston going up. Some diesels have glow plugs too that heat up the air fuel mixture so it is more easily ignited.
When a volume of air is compressed its temperature does it increase or decrease or neither?
There is a thing called the "heat of compression" which causes all compressed substances to increase in temperature.
