We are given with:
Q = 700 J
W = 400
U1 = 1200 J
From the first law of thermodynamics
Q = ΔU + W
Q = U2 - U1 + W
U2 = Q - W + U1
U2 = 700 - 400 + 1200
U2 = 1500 J
We are given with
Q = 500 J
W = 300 J
U1 = 1500 J
U2 = 500 - 300 + 1500
U2 = 1700 J
<span>the answer is 1) 1500 J, 2) 1700 J </span>

However, the war wasn't won until the French decided to help the Americans and helped them take the British Navy down.
