On a cold winter day when the temperature is -20 degrees celsius, what is the amount of heat needed to warm internal body temp(37) the .5 L of air exchanged with each breath? Specific heat of air is 1020 J/(kg K) and that 1.0L air has a mass of 1.3g.

Please help!! I dont know where to start

heat= mass*c*deltaTemp
=1.3/2 g*1.020J/gK*57K
