Let's
the transfer of energy through empty space
What is Radiation?
What is thermal energy?
When liquids change to a gas
What is evaporation?
A measure of the average kinetic energy of particles in a substance
What is temperature?
What is conduction?
A material that allows thermal energy to transfer easily
What is a conductor?
A hot air balloon is an example of this type of heat transfer
What is convention?
When two objects in contact reach the same temperature and heat no longer flows between them
What is thermal equilibrium?
This is a system that does not allow matter to get in or out
What is a closed system?
What is vacuum-insulated?
This is when there is a layer of gas particles between two walls
What is air-insulated?
When a gas changes to a liquid
What is condensation?
The movement of heat energy through a fluid of gas, like air or water, due to differences in temperature
What is convection?
Your feet burning on the hot sand on a beautiful beach day is an example of this type of heat transfer
What is conduction?
What is heat?
Cooper wire and a brass bowl would be examples of this
What is a conductor?
This is a substance that has its particles spread very far apart, have lots of empty space between them, and move very quickly
What is a gas?
The movement of energy from one object or place to another
What is energy transfer?
A material that slows down the transfer of thermal energy
What is an insulator?
Wool and plastic would be good examples of this
What is an insulator?
The energy of motion
What is kinetic energy?
This process is responsible for grass being wet in the morning even though it didn't rain and you don't have a sprinkler system
What is condensation?
This is a substance that has its particles close together but they have enough space to slide and roll past one another and take the shape of their container
What is a liquid?
What is a solid?
This is a system that allows matter in or out
What is a open system?
