Question | Answer |
---|---|
Energy | The ability to do work |
Work | The force applied to an 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 (e.g. all substances) |
Kinteic Energy | Energy that is in motion (e.g. heat) |
Metric measurement of energy | Joule |
Convert Fahrenheit to Celsius | °C = 5/9( °F-32 ) |
Convert Celsius to Fahrenheit | °F = 9/5(°C) + 32 |
Convert Celsius to Kelvin | °K = °C + 273.15 |
1 calorie | 4.184 Joules |
Calorie | The amount of heat necessary to warm one gram of water one degree Celsius |
Specific heat | The amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Celsius |
Specific heat formula | q = mc∆T where q = amount of heat absorbed or released m = mass of object c = specific heat of object ∆T = change in temperature |
Specific heat units | J/g°C or cal/g°C or cal/kg°C |
Specific heat of water | 1.000 cal/g°C or 4.184 J/g°C |
Calorimetry equation | -q(object) = q(water) + q(calorimeter) |
