Question 1

Question

A) Based on the Law of Conservation of Energy, which of the below is true? (1 point)
Kinetic energy is equal to potential energy minus temperature.
Kinetic energy is always equal to potential energy.
Energy cannot be created or destroyed by ordinary chemical or physical means.
Potential energy is equal to thermal energy plus kinetic energy.
Question 2
A) When thermal energy is removed from particles, what action occurs? (1 point)
The particles’ kinetic energy decreases.
The particles move more quickly.
The particles’ energy is destroyed.
The particles’ temperature increases.

a heated swimming pool
a glass of refrigerated water
steam rising from a kettle
a cube of ice
