Thermochemistry: Intro and Calorimetry Flashcards

A set of vocabulary flashcards covering the introductory concepts of thermochemistry, calorimetry types, and variables used in the heat capacity equation based on the provided lecture notes.

Energy

The capacity to do work or to supply heat.

Chemical potential energy

Energy stored within a substance due to its chemical composition.

Endothermic reaction

A reaction that absorbs energy.

Law of Conservation of Energy

States that in any chemical or physical change, energy can neither be created nor destroyed, only changed in form.

Thermochemistry

The study of heat changes that occur during chemical and physical changes.

Calorimetry

The measurement of heat flow into or out of a system for chemical and physical processes.

Calorimeter

A device used to measure the amount of heat absorbed or released during chemical and physical processes.

Coffee Cup Calorimeter

A type of constant-pressure calorimeter.

Bomb Calorimeter

A type of constant-volume calorimeter.

Specific heat ($c$)

The amount of heat required to raise the temperature of $1\,g$ of a substance by $1^{\circ}C$.

$$q=mc\Delta T$$

The equation used to calculate heat energy based on mass, specific heat, and change in temperature.

$$q$$

The variable representing heat energy in the specific heat equation.

$$m$$

The variable representing mass, typically measured in grams ($g$), in the specific heat equation.

$$c$$

The variable representing specific heat capacity in the specific heat equation.

$$\Delta T$$

The variable representing the change in temperature.

Specific heat of $H_2O$

The value used for water in heat calculations, defined as $1.00\,cal/g^{\circ}C$ (or approximately $4.184\,J/g^{\circ}C$).
