If the question is "How IS gas affected when it is heated":
When gas is heated, it's volume increases (it expands).
If the gas is contained within a chamber, the pressure will increase instead.

When coal is heated in the absence of air what is the gas called?
coal tar
Why must coal be heated in the absence of air to change into coke?
Because the oxygen in the air would cause it to combust rather than turn into coke (+coal gas).
When a liquid is heated how does its volume change?
When a gas is heated, its' volume increases.
Does gas expand when heated?
Yes. Typically, a gas will approximately expand according to the ideal gas law; this means that if you double the temperature (expressed in kelvin), and keep the temperature constant, the volume will approximately double.
Why does heated gas become lighter?
Heated particles are not actually lighter. What happens is that heated particles require more area. This increase in area is observed as an increase in volume. This reduces the number of particle in a given space. This means that the heated air is less dense. Due to buoyancy, things that are less dense "float" on top of denser things. This is why a hot air balloon rises.

How is air pressure affected when an areas of earth is heated?
It expands, rises, and becomes less dense.
In winter what heats the air in your house?
Gas heated hot water radiators.
Which gas is used in hot air balloons?
Just regular air, which is heated. That's why they are called hot air balloons! The fuel gas used for heating the air is usually propane.
What kind of gas is used for air balloon?
Just plain old ordinary air, but heated by the flame of the burner (which I believe burns propane gas).
What gas or liquid is released when magnesium is heated?
When magnesium is heated, it undergoes a chemical reaction with oxygen in the air, resulting in the release of a gas called magnesium oxide (MgO).
How does a Gas Clothes Dryer work?
A gas dryer uses natural gas to heat air which is then passed through a rotating drum which tumbles the clothes through the heated air.
What happens the air when it is heated by the sun?
Like any other gas, air expands when it is heated. As the heat rises and the air spreads out, pressure decreases. this because pressure is the amount of force exerted on a specific area. Therefore, as gas spreads, it pushes less and over a larger area. so.... when heated by the sun, air pressure would technically decrease
How solids change into gases?
They have be heated to liquid form first, and from that they must be heated more to be able to evaporate into the air and become a gas.
What does cold air have more than hot air?
Cold air is more dense than hot air. This is because gas expands when it is heated.
What gas expands when heated?
all gases. The volume of a gas is directly proportional to the temperature, and inversely proportional to pressure. Maybe you mean air, but air is a mixture of gases
What happens to gas in a balloon when that gas is heated?
The gas will expand as it is heated.
