The internal energy of a gas is given by $U = 2 P V$ . It expands from $V_{0}$ to $2 V_{0}$ against a constant pressure $P_{0}$ . The heat absorbed by the gas in the process is:

Options:

Answer:

Solution:

$Δ U = 2 P_{0} (2 V_{0}) - 2 P_{0} V_{0} = 2 P_{0} V_{0}$ , $W = P_{0} V_{0}$ , so $Q = 3 P_{0} V_{0}$ . C.
