Suppose the pressure of the bulb (light bulb I'm guessing used in experiment) is 20 psi (absolute) at 20C. What would you predict the pressure to be at 0C? What would you predict would be at 100C?

I used the ideal gas law equation P = nRT/V and got:

0C Pressure = 18.6 psi

100C Pressure = 25.5 psi

How'd I do? Did I get it right? Big Thanks!!!
