Thermal & Light Energy Transfer

Heat transfer is the movement of thermal energy from one object to another, typically occurring from warmer objects to colder ones.

Molecules in a solid are closely packed together and vibrate in place, maintaining a fixed shape.

Kinetic energy is the energy of motion, which increases as the speed of an object increases.

As temperature increases, molecules move faster due to increased kinetic energy.

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

Conduction is the transfer of heat through direct contact between materials.

Convection is the transfer of heat through the movement of fluids (liquids and gases) caused by differences in temperature.

Radiation is the transfer of energy through electromagnetic waves, such as sunlight.

Thermal energy is the total energy of particles in a substance, while temperature measures the average kinetic energy of those particles.

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.
