KillGorack / Physics 2010 / If an ideal gas does positive work on its surroundings, we may assume, with regard to the gas: 1) temperature increases. 2) volume increases. 3) pressure increases. 4) internal energy decreases. 5) both choices B and C are valid.

The following physics responses are provided by a student and, as such, should be considered in that context. While every effort is made for accuracy, absolute correctness cannot be fully guaranteed.

Question If an ideal gas does positive work on its surroundings, we may assume, with regard to the gas: 1) temperature increases. 2) volume increases. 3) pressure increases. 4) internal energy decreases. 5) both choices B and C are valid.
Answer volume increases.
