We usually set the fan speed to keep the temperature rise of the air passing through the system between roughly 40F-65F depending on the age and efficiency of your system. So, return air temperature may be 70F which means that the supply air measured in the furnace would be 110F to 135F.
exists and is an alternate of . Carbon dioxide is denser than air. The density of carbon dioxide is 1,977 g/L at 0 0C and standard pressure. The density of air (the so called International Standard Atmosphere) is 1,225 g/L.

hot air holds more moisture than cold air in what way are air molecules different during the summer than in the winter in the summer they move faster and farther apart on a hot day, water forms on the outside of a glass. where does the water come from the air/ water vapor what happens to the particles of a substance as thermal energy increases
