A cylinder is made of perfectly thermally insulating material so that its contents are thermally isolated from the environment The cylinder contains an ideal gas It is closed with a piston that is free to move vertically but fits tightly such that no gas leaks out of the cylinder There is no friction between the piston and the cylinder walls Additional masses Ideal gas Cylinder with thermally insulating walls Initially there are some small masses on top of the piston Many additional small masses are then added one by one to the piston very slowly The process ends when all the small masses have been placed on top of the piston Which of the following statements are correct i The initial and final temperatures of the gas are the same ii The internal energy of the gas increases iii The energy transferred thermally to the gas during the process is zero i e Qto gas 0 O ii and iii O i only O All of the statements are correct O ii only O iii only O i and ii O i and iii None of these statements are correct
