Heating a gas increases when its volume if the pressure remains constant.
Heating a gas will increase its volume, according to equation of state, law of thermodynamics. The volume is directly proportional to the temperature multiplied by the constant that is unique to each gas. The volume of the gas will expand until the gas dissipates unless it is placed into a container.
The volume would increase as the pressure of the expanding air increases.

yes
When a gas is heated, its' volume increases.
The volume of a substance increases when heated
No, the volume of a metal increases as it is heated. It expands.
The volume of air increases on its heating hence the balloon rises on heating
As air (unconfined), is heated its volume increases, and its density decreases. That makes it lighter (per volume) than it was. Warm air will rise above colder air, and in essence, float on top of the colder air.
The volume of a substance increases when heated, causing a decrease in density.
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.
It decreases
The air expands.
