1. The problem statement, all variables and given/known data A 22 cm diameter vertical cylinder is sealed at the top by a frictionless 25 kg piston. The piston is 75 cm above the bottom when the gas temperature is 316 C. The air above the piston is at 1.00 atm pressure. 1)What is the gas pressure inside the cylinder? 2)What will the pressure be if the temperature is lowered to 12 C? 3)What will the height of the piston be if the temperature is lowered to 12 C? 2. Relevant equations pV=nRT 3. The attempt at a solution Ill be honest im completely lost in this problem and really need some help.
