| External forces on the gas performed work of 300 J, while the internal energy of the gas increased by 400 J. How much heat was transferred to the gas.
Given:
A = 300 J
ΔU = 400 J
Find: Q =?
Decision:
According to the first law of thermodynamics
ΔU = Q + A
Q = ΔU – A
Q = 400 J – 300 J = 100 J
Answer: Q = 100 J.
