Describe the structure of a Liquid
Weak forces of attraction. Close particles that can move over another in irregular arrangements. 2nd most dense state. Move in random directions at low speeds.
3 of 12
Describe the structure of a Gas
No forces of attraction. Lowest density. Particles are free to move around and travel in random directions at a range of high speeds
4 of 12
What is internal energy?
The total energy that its particles have in their kinetic and potential energy stores
5 of 12
What increases internal energy? What does this do to the system?
Heat, and the system changes state/changes temperature.
6 of 12
What are the changes of state?
Solid - Freezing/Melting - Liquid - Boiling/Condensing - Gas
7 of 12
What is the equation for Specific Latent Heat?
L = Energy / Mass
8 of 12
What is Specific Latent Heat?
Amount of energy needed to change 1kg of a substance from one state to another without changing its temperature.
9 of 12
What is the specific latent heat for changing between a solid and liquid?
Specific latent heat of vaporistation
10 of 12
