If the temperature and number of moles remain constant, volume is inversely proportional to pressure. If the pressure goes up by a factor of 2, the volume will decrease by a factor of 2. Write this as an equation. P. They are indirectly proportional. It will increase by a factor of 4.
Volume is directly proportional to absolute temperature.
The pressure is directly proportional to the absolute temperature. Calculate the temperature required. In previous problems, only two variables were changing. Specifically, we will first change the temperature and look at the change in volume, and then apply the pressure change to the new volume. Determine the number of moles of gas using the ideal gas equation.
