Chemistry Module 2
Heat, Energy, and Temperature
| Term | Definition |
|---|---|
| Energy | The ability to do work |
| Work | The force applied to a object times the distance that the object travels parallel to that force |
| Heat | Energy that is transferred as a consequence of temperature differences |
| First Law of Thermodynamics | Energy cannot be created or destroyed, it can only change form |
| Potential Energy | Energy that is stored. |
| Kinetic Energy | Enery that is in motion. |
| Joule | Metric measurement of energy |
| Formula for converting Fahrenheit to Celsius | °C = 5/9( °F-32 ) |
| Formula for converting Celsius to Fahrenheit | °F = 9/5(°C) + 32 |
| Formula for converting Celsius to Kelvin | °K = °C + 273.15 |
| Calorie | The amount of heat necewssary to warm one gram of water one degree Celsius |
| 1 Calorie = _______ Joules | 4.184 |
| 1 Food Calorie = _______ chemistry calories | 1000 |
| Specific Heat | The amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Celsius |
| Formula for Specific Heat | q = mc∆T where q = amount of heat absorbed or released m = mass of object c = specific heat of object ∆T = change in temperature |
| Units for Specific Heat | J/g°C or cal/g°C or cal/kg°C |
| Calorimeter Equation | -q(object) = q(water) + q(calorimeter) |
