After a free expansion to increase its volume by volume isobarically and then warmed up isochorically to its original temperature. what is the heat added to the gas in the final step to restoring its original state? (use the following as necessary: po for the initial pressure and vo for the initial volume.) a factor of seven, a mole of ideal polyatomic gas is compressed back to its original 3fpo0 7

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

Ithink the answer is c but then again i'm probably wrong

Iwas going to ask that quesytion  sorry dude i dont  know : (    : /
