Answer to Question #202066 in General Chemistry for Matt
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.
