School's probably out on this one, but here's practicing an answer:

Assuming the sample behaves as an ideal gas, PV = nRT enables predicting what happens under the change in conditions specified. Using subsripts to describe the before (b) and after (a) conditions: Pa/Pb = TaVb/TbVa. In the first case, the pressure would be 1/6 after and four times more in the second case.
