145g, and You have built a thermometer out of a piston in a cylinder. The piston has a mass m, a radius of r = 12.5cm. To calibrate the thermometer, you place it in a bath of ice water, which has a temperature of T; = 273K. You then fill it with nitrogen gas (N2), which causes the piston to rise to a height of y; = 8.50cm once it reaches an equilibrium with the ice water. You then put your calibrated thermometer in a room and allow it to reach a thermal equilibrium with the air. You note that the height of the piston is now yf = 9.50cm. Assume the nitrogen to be an ideal gas.

Q1 Please help me understand this

Q1] You have built a thermometer out of a piston in a cylinder. The piston has a mass m, a radius of r = 12.5cm. To calibrate the thermometer, you place it in a bath of ice water, which has a temperature of T; = 273K. You then fill it with nitrogen gas (N2), which causes the piston to rise to a height of y; = 8.50cm once it reaches an equilibrium with the ice water. You then put your calibrated thermometer in a room and allow it to reach a thermal equilibrium with the air. You note that the height of the piston is now yf = 9.50cm. Assume the nitrogen to be an ideal gas. 145g, and a) What is the gauge pressure in the thermometer after coming to thermal equilibrium? b) How many moles of N2 were in the thermometer? c) What is the air temperature in the room?
