Topic: Temperature

Question 9 IGCSE_MODEL_QUESTIONS_VOL1 • 2023 • PHYSICS • essay

A sealed cylindrical steel container has an internal length of 0.500 m and an internal diameter of 0.100 m. It contains 0.16 mol of an ideal gas at a temperature of 300 K and a pressure of 1.0×10^5 Pa. The container is heated uniformly until the gas temperature reaches 400 K. Steel expands linearly with a coefficient of linear expansion of 12×10^-6 K^-1.

Question Parts

( a )

Assuming the dimensions of the container do not change, calculate the new pressure of the gas after heating.

( b )

Now take the thermal expansion of the steel into account and calculate the new pressure of the gas.

( c )

Explain qualitatively how the final pressure would be affected if the container were made of a material with a much larger coefficient of linear expansion.
