Question #202066

The surroundings do 1.44kJ of work compressing a gas in a perfectly insulated cylinder such that no heat can be exchanged. "Calculate the change in internal energy of the system and determine whether the process is endothermic or exothermic"

Expert's answer

ΔE = q + w

q = 0 in a perfectly insulated cylinder such that no heat can be exchanged.

ΔE = 0 + 1.44 = 1.44 kJ

The process is isothermic.
