Kinetic/Potential Energy
The inside of a car gets hot on a sunny day. What form of heat transfer is shown?
What is radiation?
What is convection?
The transfer of heat through fluids (liquids or gases).
What is radiation?
The transfer of energy through electromagnetic waves.
What is conduction?
What is.....The transfer of heat through direct contact between particles.
Eggs cooking on a hot frying pan. This shows what form of energy transfer?
What is conduction?
What happens to particles during conduction?
They collide and transfer energy.
Give an example of radiation.
The Sun warming the Earth
Give an example of conduction
What is.....A metal spoon getting hot in a pot of soup.
What form of energy travels as waves?
Radiant energy.
Give an example of convection.
Boiling water where warm water rises and cool water sinks.
Does radiation require matter?
No, it can travel through empty space.
What type of material transfers heat well?
What is....A conductor, such as metal.
Why does warm air rise?
Because it is less dense than cool air.
Name two forms of energy.
Thermal, electrical, radiant, mechanical, kinetic, potential.
What is an insulator?
A material that resists the flow of heat or electricity.
Energy of the movement of atoms and molecules in relation to heat.
What is thermal energy?
Why does wood feel warmer than metal at the same temperature?
Wood is an insulator and doesn’t transfer heat easily.
This is a type of energy that travels in waves and can travel through empty space.
What is radiant energy?
Give one example of a conductor and one of an insulator.
Conductor: copper; Insulator: rubber.
