Consider a sample of helium gas with a mass of 7.0 g, an initial pressure of 2.0 atm and an initial temperature of 25°C. Helium is compressed at constant pressure until its volume is reduced to one-third of its initial value. Determine the final temperature of the gas.

How much heat energy is transferred from a 4.00 g of oxygen gas that initially has a volume of 2.50 liters and a pressure of 4.0 atm, and is then compressed at constant pressure until the volume is reduced by half, and finally undergoes an isochoric process until the gas reaches its original temperature of 25.0°C?  

A chef wants to reduce the cooking time by a few minutes. To succeed, he raises the pressure to 4 atm inside the cooker. At this pressure, the boiling point of water, the density of water, and the density of steam are 144 °C, 922.2 kg/m³, and 2.163 kg/m³ respectively. What is the work (W) done by 200 g of steam formed at 144 °C inside the cooker?

During a laboratory experiment, a student uses a piston-cylinder assembly initially containing 10 cm³ of an ideal gas. The cylinder is heated with an electric resistor to maintain constant pressure of the expanding gas. The net energy added to the gas by heat is 5 J and the pressure sensor inside the cylinder indicates a value of 3 × 10⁵ Pa. Find the work done by the gas if the volume of the cylinder is doubled.

A gas enclosed in a piston-container assembly loses 340 J of heat as it is compressed from 450 cm³ to 200 cm³ at constant pressure. The internal energy of the gas increases by 220 J. Calculate the pressure during the process.

A model of the lungs can be made using a balloon inside a container fitted with a movable piston. The balloon is connected to the atmosphere using a pipe. Air is sucked into the balloon when the piston is lowered and expelled when the piston is raised. An idealized curve with straight lines instead of curves for sucking and expulsion is shown below. Note: The curve is labeled using gauge pressure rather than absolute pressure. Determine the net work done by the ballon in one cycle. 

An ideal gas in a container with a piston is taken through a two-step process. In the initial step, volume is kept constant at 0.800 m³ as the pressure is raised from 0.980 × 10⁵ Pa to 4.20 × 10⁵ Pa. In the subsequent step, the gas is compressed, keeping the pressure constant at 4.20 × 10⁵ Pa to a final volume of 0.450 m³. What is the total work done during this two-step process?
