Quarter 3 Ranger Monster Hunt #4: Heat Transfer

A fundamental principle stating energy cannot be created nor destroyed but only changed from one form to another.

• Conservation of energy

• Touching a metal handle of a hot pan.

• Electromagnetic spectrum

• A person placing their cold hands over a warm fire

Transfer of energy from higher temperature objects to lower temperature objects.

• Heat

• Electromagnetic spectrum

• Celsius

• Insulator

A measure of the AVERAGE kinetic energy of the particles in a sample of matter.

• Temperature

• Heat

• Using a heating blanket to get warm

• Conservation of energy

The process whereby heat moves from one body or substance to another by radiation, conduction, convection, or a combination of these methods.

• Electromagnetic spectrum

• Heat transfer

• Putting your wet shoes on a floor vent to dry them faster

• A person placing their cold hands over a warm fire

A material that transfers energy easily; metals

• Conductor

• Using a heating blanket to get warm

• Conduction

• Putting your wet shoes on a floor vent to dry them faster

Heat transfer by direct contact/TOUCH

• Conduction

• A person getting warm from a space heater.

• Picking up a hot cup of coffee

• Heat transfer

Heat transfer through air and water; warm goes up because it is less dense due to particles moving faster and spreading apart, and cold goes down because the particles slow down and move closer together making them more dense.

• Touching a metal handle of a hot pan.

• Convection ✔

• Celsius

• Picking up a hot cup of coffee

A material that does not allow thermal energy to transfer easily.

• Lying out in the sun to get a tan

• Touching a metal handle of a hot pan.

• Insulator

• Electromagnetic spectrum

The transfer of energy as electromagnetic waves through space, sun, and fire.

• Conductor

• Radiation

• Touching a metal handle of a hot pan.

• Conservation of energy

Waves that can transfer electric and magnetic energy through the vacuum of space.

• Radiation

• Putting your wet shoes on a floor vent to dry them faster

• Electromagnetic waves

• Insulator
