Question:

A) If the number of molecules in an ideal gas is doubled, by how much does the pressure change if the volume and temperature are held constant?
B) If the volume of an ideal gas is halved, by how much does the pressure change if the temperature and number of molecules is constant?
C) If the temperature of an ideal gas changes from 200 K to 400 K, by how much does the volume change if the pressure and number of molecules is constant.
D) Repeat part C) if the temperature changes from 200 C to 400 C.
