Question

An ideal gas is sealed in a container at constant volume. if the temperature t is increased to 4t, the pressure will be:

Answer 1

I believe that it would increase to 4p

Answer 2

The pressure is proportional to the ABSOLUTE temperature. If the ABSOLUTE temperature increases by a factor of 4, the pressure will too ... to 4p. The ABSOLUTE temperature is the number of degrees above Absolute Zero. So for example, if the gas started out at, say 100 CELSIUS, you'd have to heat it to 1219 Celsius, because Zero Celsius is 273 Kelvin (absolute).
