Consider an ideal gas contained in a confined volume. How would the pressure of the gas change if..
1. The number of molecules of the gas was double, without changing the container or the temperature?
2. The volume of the container was doubled, without changing the number of molecules or the temperature?
3. The temperature (in K) of the gas was doubled, without changing the number of molecules or the volume of the container?
4. The rms speed of the molecules was doubled, without changing the number of molecures or the volume of the container?
