For a gas of a fixed volume and mass, the pressure when divided by its temperature, , is 0.16 kPa/K. To what temperature must the gas be heated in order to produce a pressure of 40 kPa?
A sealed container contains 0.4 m3 of helium gas at a temperature of 400 K and a pressure of 50 kPa. The temperature of the gas is halved while the volume is kept constant. Then, the volume is reduced to a quarter of its original value while the temperature is kept constant. What is the final pressure of the helium?
The graph shows the pressure and temperature of a gas as it undergoes two processes. The gas initially has a temperature of 100 K and a pressure of 35 kPa. Line on the graph shows the gas being heated to 500 K at a constant volume. Line on the graph shows the gas changing in volume while the temperature remains constant at 500 K.
By what factor does the volume of the gas increase after undergoing these two processes?
