A sample of a gas is in a sealed container. The pressure of the gas is 625 torr, and the temperature is 21 °C. If the temperature changes to 75 °C with no change in volume or amount of gas, what is the new pressure, P2, of the gas inside the container? Express your answer with the appropriate units.
Using the same sample of gas (P1 = 625 torr, T1 = 21 °C), we wish to change the pressure to 6250 torr with no accompanying change in volume or amount of gas. What temperature T2, in Celsius, is needed to reach this pressure? Express your answer with the appropriate units.
