Question

At the one bar pressure the volume of gas is
0.6 litre. If the gas receives 122 Joule of heat at
1 atmosphere pressure, the volume become
2 liter the calculate its internal energy. (1 litre
bar = 101.32 Joule)

Answer 1

Explanation:

∆U=Q+W

=120+P∆V

=120+(101.32 * 1.4)

=120+(141.848)

∆U=261.848 Joule
