Internal energy

Question 1

What is internal energy?

Answer 1

Internal energy is the total energy contained within a system, including both kinetic and potential energy at the molecular level.

Question 2

True or False: Kinetic energy is the energy possessed by an object due to its motion.

Answer 2

True

Question 3

Fill in the blank: Potential energy is energy that is stored due to an object’s _______.

Answer 3

position

Question 4

Potential energy is greater/smaller when there is a larger space between particles like gas

Answer 4

greater

Question 5

What are the 2 scenarios that could happen when you increase internal energy

Answer 5

1. • kinetic energy store increases
   • state stays the same
   • temperature increases

2.
- potential energy store increases
- state changes
- temperature stays the same

Question 6

internal energy formula

Answer 6

internal energy = potential energy + kinetic energy
