Harper Vance · Answer 1

According to first law of thermodynamics:

Q = ΔE + W

Q is heat added, ΔE is increase in the internal energy of the system and W is work done by the system.

Here Q = 36 KJ

ΔE = 14 kJ

Putting the values in the equation

36 = 14 + W

W = 36 - 14

= 22 kJ.

Work done by gas or system = 22 kJ.
