A cylinder with an ideal gas has a piston of mass m = 5kg on it which can slide up and down and does not permit the gas to escape. The inner radius of the cylinder is r = 6cm, The top of the piston is open to atmospheric pressure. The entire system is initially in thermal equilibrium with the environment, which is at 20°C and the height of the piston 10cm. If the temperature of the gas inside then is raised to 100°C, what is the final height of the piston? h A 20 cm В 50 cm 12.7 cm D 25.4 cm E 18 cm Open to outside air, pressure po Piston, mass m Ideal gas

A) A rigid tank contains 1.60 moles of helium, which can be treated as an ideal gas, at a pressure of 28.0 atm. While the tank and gas maintain a constant volume and temperature, a number of moles are removed from the tank, reducing the pressure to 5.00 atm. How many moles are removed? B) What If? In a separate experiment beginning from the same initial conditions, including a temperature Ti of 25.0°C, half the number of moles found in part (a) are withdrawn while the temperature is allowed to vary and the pressure undergoes the same change from 28.0 atm to 5.00 atm. What is the final temperature (in °C) of the gas?

On a chilly 10°C day, you quickly take a deep breath—all your lungs can hold, 4.0 L. The air warms to your body temperature of 37°C. If the air starts at a pressure of 1.0 atm, and you hold the volume of your lungs constant (a good approximation) and the number of molecules in your lungs stays constant aswell (also a good approximation), what is the increase in pressure inside your lungs?

An ideal diatomic gas undergoes an adiabatic compression during which time its volume changes from VA = 1300 cm3 to VB = 390 cm3. If its initial temperature is TA = 74.0°C, what is the final temperature TB of the gas?

A cylinder of cross sectional area 0.0287 m^2 is filled with an ideal monoatomic gas. A mass of 47.4 kg is placed on top of the piston which is free to move without friction. The piston starts 0.61m above the base of the cylinder. The gas in the piston is initially at a temperature of 454.0 K and the pressure in the lab is 100kPa.How many moles of gas are in the cylinder?
