A. Which of the following statements is true for a gas contained in a box with a piston?
1. Some but not all isothermal expansions are adiabatic.
2.An isothermal expansion is never adiabatic.
3.Every isothermal expansion is adiabatic.
4.Every expansion is either isothermal or adiabatic.
B. Doubling the gauge pressure of an ideal gas, while keeping the volume of the gas fixed, implies that the temperature changes how?
There is not enough information to solve this.
The temperature halves
The temperature doubles.
The temperature stays the same.
C. A pressure gauge measures the pressure of your bike tires by connecting to the inside of the tire via a small tube. The reading shows six atmospheres. If you were to replace that tube by another one that has twice the diameter of the original, what pressure would you read?

An ideal monatomic gas is contained in a cylinder with a movable
piston so that the gas can do work on the outside world, and heat
can be added or removed as necessary. The figure shows various
paths that the gas might take in expanding from an initial state
whose pressure, volume, and temperature are , , and respectively. The gas expands to a state with
final volume . For some answers it will be convenient to

1.Argon contained in a closed, rigid tank, initially at 62.3°C, 3.9 bar, and a volume of 4.2 m3, is heated to a final pressure of 9.4 bar. Assuming the ideal gas model with k = 1.6 for the argon, determine the heat transfer, in kJ. 2.Water vapor contained in a piston–cylinder assembly undergoes an isothermal expansion at 223°C from a pressure of 5.4 bar to a pressure of 1.9 bar. Evaluate the work, in kJ/kg. 3.A mass of 4 kilograms...

1.Water vapor contained in a piston–cylinder assembly undergoes an isothermal expansion at 277°C from a pressure of 5.1 bar to a pressure of 2.7 bar. Evaluate the work, in kJ/kg. 2.Nitrogen (N2) contained in a piston–cylinder arrangement, initially at 9.3 bar and 437 K, undergoes an expansion to a final temperature of 300 K, during which the pressure–volume relationship is pV1.1 = constant. Assuming the ideal gas model for the N2, determine the heat transfer in kJ/kg. 3.Argon contained in...

1 kg air is contained in an INSULATED piston-cylinder device. Initially, the temperature and pressure of the gas are T = 300 K and P = 200 kPa respectively. Work is extracted from the gas until the pressure of the gas reaches to Pfinal. Calculate Pfinal according to the last digit of your student number. Students with “00” as the last digit should take Pfinal = 100 kPa and Students with “99” as the last digit should take Pfinal =...

Identify which of the following statements is true about ideal gas behavior in a closed container. Select the correct answer below: If the temperature increases while the volume remains the same, the pressure also increases. If the temperature increases while the pressure stays the same, the volume decreases. If the pressure increases while the volume stays the same, the temperature decreases. If the volume increases while the temperature stays the same, the pressure also increases.
