A 750 ml sample of hydrogen exerts a pressure of 822 torr at 325 K. What pressure does it exert if the temperature is raised to 475 K at constant volume? I know the answer is 1.20 x 10^3 torr but I don't understand how that was reached. I am confused as to which gas laws are used when. If someone could provide a step by step of this problem and briefly describe when to use which gas laws I would appreciate it!
