Heat and Calorimetry
| HEAT AND CALORIMETRY | |
|---|---|
| Heat | The transfer of energy between a system and its surroundings due to a difference in temperature. |
| Conduction | Energy transfer mediated by direct contact (an exchange of KE). |
| Convection | Energy transfer by movement of a fluid. |
| Radiation | Energy transfer by electromagnetic radiation. |
| Specific Heat | Heat required to raise the temperature of 1g of a substance 1°C. q = mcΔT m = mass c = specific heat ΔT = Tf - Ti |
| Latent Heat of Fusion | Heat required to melt 1kg of a substance at its melting point. |
| Latent Heat of Vaporization | Heat required to boil 1kg of a substance at its boiling point. |
