internal energy Flashcards
1
Q
what is internal energy?
A
- the total kinetic energy and potential energy of all
the particles that make up a system
2
Q
what is energy in a system stored by?
A
the particles that make up the system
3
Q
how does heating change the energy stored?
A
- by increasing the energy of the particles that make up the system
- means they gain kinetic energy so move faster, increasing internal energy
- leads to a change in temp, or a change in state
