What are the two major characteristics that change when air is heated and cooled?
Since we are talking abut heating and cooling - we define those both as changing the temperature so that is one characteristic. Other characteristics depend on how the heating and cooling occur. If the pressure remains the same, air will expand on heating and contract on cooling. If the volume is held constant, the pressure will increase with heating and decrease with cooling. The internal energy depends on what you do with pressure, work and heat. You can actually get a warmer gas with less internal energy and a cooler gas with more internal energy.
What are two major characteristics that change when air is heated and cooled?
It depends on how high you heat or cool the air. The density and entropy as functions of temprature would be affected mostly. By heating the air density decreases and entropy increases.

What happens when cooled air meets heated air in an enclosed chamber?
Precipitation is usually the result of warm air meeting cold air currents.
How does air behave as it is warmed or cooled?
when air(gas) is cooled(thermal energy is removed) its molecules slow down and it becomes a liquid(condensation) when air(gas) is heated(thermal energy is added) its molecules speed up, but it wont change into a different phase until gas is heated to a temperature above 10,000 C, which removes electrons from the atoms
What is a return air grille?
A return air grille is where air returns to the furnace to be filtered and heated or cooled and re circulated through the air supply grilles.
Why does a hot air balloon rise when it is heated and sink wen it is cooled?
If it is cooled its gets extremely cold from the helium,and when the heat is in the balloon it keeps it warm when its in the helium
Why does temperature affect the air pressure?
Air temperature and air pressure are inversely proportional. As temperature increases, air pressure decreases. This is best demonstrated in an enclosed vessel.
How does an air cooled chiller work?
The air cooling of a chiller signifies , the cooling of radiator. in a chiller the compressor compressors the gas which on expansion cools in side Copper tubes causing the chilling effect. The refrigerants get heated up when compressed in a compressor. this heated refrigerant is cooled by blowing air in air cooled chillers. There are also water cooled chillers.
What is the purpose of the return air grill?
Air travels through the return air grill to get to the furnace, where it is filtered, heated or cooled and re circulated through the air supply grilles.
Why a cold air return is needed in a furnace?
A cold air return is similar to a return air grille, which is needed for air to travel to the furnace to be filtered, heated OR cooled and then recirculated.
