Answer:

2400 J

Explanation:

For the purposes of this question, we will treat nitrogen as an ideal gas. Thermal energy is calculated in the following way:

thermal energy =  1.5nRT

But since PV = nRT

then thermal thermal energy  = 1.5PV

thermal energy = 1.5 * 1.6×10^4 cm³ * 100 atm

                          = 1.5 * 16 L * 100 atm = 2400 J
