A 700 g quantity of an ideal gas undergoes a reversible isothermal compression at a temperature of 330 K The compression reduces the volume of the gas from 0.40 m3 initially, to 0.15 m3 finally. The molecular mass of the gas is 380 g/mol What is the entropy change for the gas, in SI units?

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
