Gce Model Questions Vol1 2020 Physics Question 14
Practice objective / multiple choice question 14 from the 2020 Gce Model Questions Vol1 Physics examination.
A sealed container of volume \(V=0.020\,\text{m}^{3}\) contains \(n=0.50\) mol of an ideal gas at an initial temperature of \(300\,\text{K}\). (a) The gas is heated until its pressure doubles. Find the temperature after this heating step. (b) Keeping the temperature constant at the value found in part (a), the gas expands isothermally until its pressure returns to the original value. Determine the final volume. (c) Calculate the total change in internal energy of the gas over the whole process, assuming the gas is monatomic. Use \(R=8.314\,\text{J mol}^{-1}\text{K}^{-1}\).
