- Kinetic theroy
- can be used to explain conduction, convection, evaporation and condensation.
- all the states of matter are made of Particles, atoms or molecules
- solids: vibrate liquids: move bu contact with other particles gases: free to move
- LIQUIDS: have a fixed volume, take the shape of their container, have a medium particle energy
- GASES: fill the space available, have a high particle energy
- SOLIDS: fixed shape, low particle energy
- Conduction
- How do particles explain conduction
- Heat energy can move through substance by conduction Heat energy is from the hot end of the object to the cold
- Metals are good conductors of thermal energy
- Infrared Radiation
- Independent variable: surface of cube. Dependent variable: temperature of surrounding air. Controlled variable: same starting temp of water.
- Black Matt is the best absorbed and is the best emitter of thermal energy.
- Black Matt radiates the most thermal energy, because the energy surface absorbs and emits thermal energy
- Heat and Temperature
- Heat is a form of energy
- thermal energy is transferred from warm regions to cool regions
- If the temperature outside is 1 degree Celsius, there is a constant thermal transfer and we start to feel cold
- Kinetic theroy
