Internal Energy Flashcards
1
Q
What is internal energy
A
Total energy that its particles have in their kinetic and potential energy
2
Q
How can you increase the internal energy
A
Heating the system transfers energy to its particles
3
Q
What does heating a system lead to
A
Change in temp or state, if the temp changes, the size of the change depends on the mass of the substance, what it’s made of (specific heat capacity) and the energy input
4
Q
What is the process of a solid turning into a liquid called and vice versa
A
Melting
Freezing
5
Q
What is the process of a liquid turning into a gas and vice versa
A
Boiling or evaporating
Condensing
6
Q
What is the process of a solid turning into a gas called
A
Sublimating
7
Q
How is mass conserved
A
The number of particles don’t change, they’re just arranged differently
