Air Heat Capacity (Chemistry)

Factual Questions
1

I am looking for the specific heat capacity of air, however after searching all I can find is the heat capacity in J per kilograms degrees celsius and that value is 1.0 x 10^3. Question 1: Is that the correct value for the specific heat capacity of water? Question 2: I know I can easily use the kg value, but how would I convert the kg to g?

Thank you everyone! :slight_smile:

Your heat capacity number is right for dry air, but things change when it gets humid.
Your 1000 J/kg°C converts to 1.0 J/gm°C.

Just in case you need it:
Air at STP (0°C, 760 torr) has a density of 1.293 kg/m[sup]3[/sup].
1 cubic meter is 1000 liters, which at STP, holds 44.64 moles of gas.
