6.2 Open Sci Ed Thermal Energy Review

Energy is transferring out of it.

Condensation.

A system in which no matter can enter or exit.

Energy is transferred.

Matter has mass and takes up space; liquids and gases are made of particles of matter.

Thermal energy is the total energy of all the particles in an object, related to temperature.

Evaporation is the process of a liquid turning into a gas, while condensation is the process of a gas turning into a liquid.

Temperature measures the average kinetic energy of particles; higher temperatures mean higher energy.

Conduction is the transfer of thermal energy through direct contact between materials.

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).
