Suppose you take and hold a deep breath on a chilly day, inhaling 3.0 L of air at 0°C and 1 atm. a. How much heat must your body supply to warm the air to your internal body temperature of 37°C? b. By how much does the air’s volume increase as it warms?
a. The amount of heat is 0.103J
b. The volume is 0.408L
The amount of heat that increase1 the degree temperature of 1-mole substance is called specific heat.
As per 3-litre air, mass is
The temperature difference is
Specific heat of air is
b. As this process is an isobaric process
Applying all values
It can be said that13.6% increase that means 0.408L is the volume
