Detailed explanation-1: -The air we inhales from the surrounding is at outside temperature(consider it as 26 degree Celsius). The air we breathe out is mainly carbon dioxide from our body so the air has the temperature of our body(37 degree Celsius temperature), it is much higher than the temperature of air we breathe in.
Detailed explanation-2: -Expired air is warmer than that of inspired air because, expired air was in direct contact of respiratory passage (body temperature) which makes it warmer.
Detailed explanation-3: -In exhaled air, carbon dioxide percentage is ten times higher than atmospheric CO2 and oxygen is 16% instead of 21% which we find in the atmosphere. Plus there is some moisture in the exhaled air. Q. Inhaled air contains more water vapour than exhaled air.
Detailed explanation-4: -Answer 1: The air that leaves our bodies is about 98 o Fahrenheit, or 37 o Centigrade. If we’re blowing on food that is hotter than that, our breath will cool it. If we’re blowing on food that is colder than that, our breath will warm it.
