An 80.0 g sample of a gas was heated from 25 ∘ C to 225 ∘ C. During this process, 346 J of work was done by the system and its internal energy increased by 9015 J. What is the specific heat of the gas?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage
