Which best summarizes what happens to the system after heat is added? kinetic energy within the system decreases and creates mechanical energy as the piston moves upward. kinetic energy within the system increases and is transformed into mechanical energy as the piston moves upward. mechanical energy within the system increases and is transformed into kinetic energy as the piston moves upward. mechanical energy within the system decreases and creates kinetic energy as the piston moves upward?

Option (b) is the correct answer.

Explanation:

When heat is added to a system then vibration between molecules of the system increases. As a result, motion of molecules increases which leads to increase in kinetic energy of molecules.

Therefore, we can conclude that out of the given options, kinetic energy within the system increases and is transformed into mechanical energy as the piston moves upward.

real, smaller and upside-down.   so the answer should be b.
