a) If the pressure and volume of a gas both increase, will the temperature increase or decrease?
b) If the pressure is doubled and the volume is tripled, by what factor must the temperature increase or decrease?
c) If the pressure of the gas is decreased by removing some of the gas, is it possible to use the above formula to predict the change in volume and temperature? Why or why not?

DrBob222,
a) PV = nRT
If the left side increases, what must the right side do? Since n and R and constant, what does that mean about T>
b) If P is doubled and V is tripled, the left side increases by a factor of 6 so the right side must ????????? by a factor of 6, too?
c) If you know how much gas was there initially and how much was removed, yes, but if no knowledge of n is available, no. Besides predicting BOTH V and T mean two unknowns.
