level questions: Temperature changes and energy
| Question | Answer |
|---|---|
| How do you change the State of a material? | Adding or removing energy from a material can change its state - active process: e.g. boiling, people add energy - passive process: e.g. evaporation, liquid slowly absorbs energy from surroundings |
| Whats Sublimation? | Material goes straight from solid to gas (without being liquid) |
| Whats internal energy? | total amount of kinetic energy and potential energy of all the particles in the system. |
| Whats the Conservation of Energy? | Assuming no energy is lost to the environment, any energy transferred to a material will be distributed between the chemical store and the thermal store of the internal energy |
