A cylinder contains nitrogen gas. A piston compresses the gas to half its initial volume. Afterward,a. Has the mass density of the gas changed? If so, by what factor? If not, why not?

A 20-cm-diameter cylinder that is 40 cm long contains 50 g of oxygen gas at 20°C.d. What is the reading of a pressure gauge attached to the tank?

A 20-cm-diameter cylinder that is 40 cm long contains 50 g of oxygen gas at 20°C.c. What is the number density of the oxygen?

A gas at 100°C fills volume V₀. If the pressure is held constant, what is the volume if (b) the Kelvin temperature is doubled?

A gas at 100°C fills volume V₀. If the pressure is held constant, what is the volume if (a) the Celsius temperature is doubled

A 6.0-cm-diameter, 10-cm-long cylinder contains 100 mg of oxygen (O₂) at a pressure less than 1 atm. The cap on one end of the cylinder is held in place only by the pressure of the air. One day when the atmospheric pressure is 100 kPa, it takes a 184 N force to pull the cap off. What is the temperature of the gas?

The interior of a Boeing 737-800 can be modeled as a 32-m-long, 3.7-m-diameter cylinder. The air inside, at cruising altitude, is 20°C at a pressure of 82 kPa. What volume of outside air, at −40°C and a pressure of 23 kPa, must be drawn in, heated, and compressed to fill the plane?

The 50 kg circular piston shown in FIGURE P18.57 floats on 0.12 mol of compressed air.a. What is the piston height h if the temperature is 30°C?

The 50 kg circular piston shown in FIGURE P18.57 floats on 0.12 mol of compressed air.b. How far does the piston move if the temperature is increased by 100°C?
