In an ideal gas with fixed amount and temperature, what happens to pressure if the volume is halved?

Explanation:
When temperature and amount are fixed, pressure varies inversely with volume. For an ideal gas, PV = nRT, and with n and T constant, the product PV stays constant. If the volume is halved, the pressure must double to keep PV the same. So the pressure doubles. The other possibilities would violate PV = constant under fixed n and T.
