Temperature

an object measure of the average kinetic energy of the particles that make up that object. Measured in kelvin’s

Thermal Energy

Is the sum of kinetic energy and the potential energy of all of the particles that make up an object.

Specific heat

is the amount of heat needed to raise the temperature of 1 kg of that material by 1C.

Conduction

Is the transfer of thermal energy by collisions between the particles that make up matter.

Convection

The transfer of thermal energy in a fluid by the movements of warmer and cooler fluid.

Radiation

is the transfer of energy by electromagnetic waves, such as light and microwaves.

Thermal insulator

is a material through which thermal energy moves slowly.

Solar collector

is a device that transforms radiant energy from the Sun into thermal energy

Thermodynamics

is the study of the relationships among thermal energy, heat, and work.

First law of thermodynamics

states that if the mechanical energy of a system is constant, the increase in thermal energy of that system equals the sum of the thermal energy transfers into that system and the work done on that system.

second law of thermodynamics

states that energy spontaneously spread from regions of higher concentration of regions of lower concentration

heat engine

is a device that converts some thermal energy into mechanical energy

internal combustion engine

is a heat engine that burns fuel inside a set of cylinders.
