Thermochemistry

Temperature

measures the kinetic energy of particles of an object or substance

kinetic energy

the energy of an object beacuse of motion

heat

the flow of energy from warmer places to cooler places due to differences in temperature

thermal equilibrium

happens when heat flows from a higher temperature object to a lower temperature object until the two objects have an equal temperature

Conduction

The transfer of heat through a solid material by direct contact of particles

Convection

The transfer of heat in a fluid (caused when hotter less dense fluids, rise, and cool more dense fluid sink)

Radiation

The transfer of heat through empty space by invisible electromagnetic rays (no matter is required for the heat transferred to occur)

Specific heat

The amount of heat needed to raise a temperature of a substance 1°C

Calories

The amount of heat required to raise the temperature of water by 1°C

endothermic reaction

energy increases over time, takes in energy from the surroundings, is cold

Exothermic reaction

Energy decreases overtime, give out energy to its surroundings, is hot

Thermochemistry

The study of heat changes that occurred during chemical reactions and physical changes of state
