Internal Energy Flashcards
1
Q
What do particles in a system do?
A
Vibrate or move around
2
Q
What energy stores do the particles in a system store their energy?
A
- Kinetic energy stores
- Potential energy stores
(Gravitational and elastic)
3
Q
What is Internal energy?
A
Internal energy is the total amount of energy that a system’s particles have in thier kinetic and potential energy stores.
4
Q
What happens when a substance is heated?
A
More energy is given to their kinetic stores causing the particles to move faster and increase the internal energy
5
Q
What happens when a substance is heated enough?
A
The particles will have enough energy in their kinetic stores to break the bonds and change the state.
