Calorimetry Practice Problems

A set of vocabulary flashcards derived from calorimetry practice problems, focusing on key terms and their definitions.

Calorimetry

The science of measuring heat changes in physical and chemical processes.

Heat Capacity

The amount of energy required to raise the temperature of a substance by 1 degree Celsius.

Endothermic Reaction

A reaction that absorbs heat from its surroundings, resulting in a temperature decrease.

Exothermic Reaction

A reaction that releases heat to its surroundings, leading to a temperature increase.

Specific Heat

The amount of energy required to change the temperature of 1 gram of a substance by 1 degree Celsius.

Equilibrium Temperature

The temperature at which two substances in contact with each other reach thermal equilibrium, meaning they have the same temperature.

Q (Heat Change)

The symbol representing the amount of heat absorbed or released in a process.

Joule (J)

The SI unit of energy; equivalent to the work done when a force of one newton moves an object one meter.

∆T (Change in Temperature)

The difference between the final temperature and the initial temperature, often represented as Tf - Ti.

Coffee-cup Calorimeter

A simple device used to measure the heat of chemical reactions or physical changes, typically insulated.
