Question 1
15 May 2023 S2
17A monoatomic ideal gas, initially at temperature is enclosed in a cylinder fitted with frictionless piston. The gas is allowed to expand adiabatically to a temperature by releasing the piston suddenly. and are the lengths of the gas columns before and after the expansion respectively. The ratio isTap an option to check your answer.
Question 2
