Question

Potential energy of the system has been converted to kinetic energy (heat); consequently, the system has ________ potential energy.

a) Higher
b) Lower
c) Unchanged
d) Zero

Answer 1

The potential energy of the system has been converted to kinetic energy (heat), so the system has b) lower potential energy.

Step-by-step explanation:

The correct option is b) Lower.

When the potential energy of a system is converted to kinetic energy, it is usually in the form of heat. This means that the system loses potential energy and gains kinetic energy in the form of heat. Therefore, the system has lower potential energy.

For example, when a ball is dropped from a height, its potential energy decreases as it falls, but its kinetic energy (heat) increases.
