A \(2.0\)-mol sample of an ideal gas is initially at \(27\ ^\circ\text{C}\) and \(1.00\ \text{atm}\) occupying \(24.0\ \text{L}\). The gas is heated until its temperature reaches \(127\ ^\circ\text{C}\) while the pressure is increased to \(2.00\ \text{atm}\). Assuming ideal behaviour, (a) find the final volume of the gas in litres, and (b) calculate the percentage increase in its internal energy.

Answer Options

A. V_f = 14.0 L, ΔU% = 25.0 %
B. V_f = 18.0 L, ΔU% = 40.0 %
C. V_f = 20.0 L, ΔU% = 50.0 %
Correct Answer D. V_f = 16.0 L, ΔU% = 33.3 %
Correct Answer
D
Correct Option:
V_f = 16.0 L, ΔU% = 33.3 %
