A 1.00 m3 container of air absorbs 6098 J of heat at a constant pressure of 1.00 atm. Air has a density of 1.20 kg/m3, a constant-pressure specific heat of 1010 J/(kg·°C), and a thermal coefficient of expansion of 3.67 10-3 (°C)-1.
(a) Find the increase in the temperature of the air.
°C
(b) Find the work done by the air.
(c) Find the increase in the air's internal energy.
