Question

The diagram shows a closed system before and after heat is added to it.
Which best summarizes what happens to the system after heat is added?
a- Kinetic energy within the system decreases and creates mechanical energy as the piston moves upward.
b- Kinetic energy within the system increases and is transformed into mechanical energy as the piston moves upward.
c- Mechanical energy within the system increases and is transformed into kinetic energy as the piston moves upward.
d- Mechanical energy within the system decreases and creates kinetic energy as the piston moves upward.

Answer 1

Answer:

B

Explanation: Answer is B because whenever there is a system; in this case a closed system, when heat is added temperature increases. When temperature increases the amount of kinetic energy will be increased thus this proves Kinetic energy is increasing and because it also mentions mechanical energy and pistons I believe that some form kinetic energy is being converted to mechanical energy. And also the fact that heat will increase any form of energy. So this explanation is satisfied by option B.

Hope this helps!
