Thermochemistry
Chapter 17.1 + Calorimetry
Term | Definition |
---|---|
Thermochemistry | the study of energy changes that occur during chemical reactions and changes in state |
Chemical Potential Energy | The energy stored in chemical bonds |
Heat | energy that transfers from one object to another due to a temperature difference |
System | the part of the universe on which you are focusing |
Surroundings | anything outside the system |
The Law of Conservation Energy | Energy cannot be created or destroyed |
Endothermic | Energy travels from the surroundings to the system, feels cold and the temperature goes down. Energy goes IN |
Exothermic | Energy travels from the system to the surroundings, feels warm and temperature goes up. Energy EXITS. |
Heat Capacity | the amount of heat needed to raise the temperature of an object 1 degree celsius. Depends on mass. |
Specific Heat | the amount of heat it takes to raise 1 gram of the substance by 1 degree celsius |
Specific Heat Equation | C = q/(m) (delta t) |
Calorimetry | measuring the heat flow to determine the caloric energy |
