Igcse Model Questions Vol1 2025 Physics Question 36
Practice objective / multiple choice question 36 from the 2025 Igcse Model Questions Vol1 Physics examination.
A sealed vertical cylinder contains \(0.020\ \text{m}^3\) of air at \(1.0\ \text{atm}\) and \(300\ \text{K}\). The gas is first heated to \(350\ \text{K}\) while the piston is locked, then the piston is released and the gas expands adiabatically until the pressure returns to \(1.0\ \text{atm}\). Assuming air behaves as a diatomic ideal gas with \(\gamma = 1.4\), calculate the final volume of the gas (in \(\text{m}^3\)) after the expansion. Give your answer to three significant figures.
