19) The volume of a given mass of an ideal gas at constant pressure is

1. directly proportional to the Kelvin temperature.
2. directly proportional to the Celsius temperature.
3. inversely proportional to the Kelvin temperature.
4. inversely proportional to the Celsius temperature.

This question is based on Charles law which states V/T = a constant. This means that V = T(a constant). This reveals that V is directly proportional to T, which represents the temperature and Kelvin not in degrees Celsius.
