Vocab
Thermal energy that flows between objects due to a difference in temperature.
What is heat?
This force changes kinetic energy into thermal energy when two objects rub against each other.
What is friction?
Conduction always occurs between two objects that are doing this.
What is touching each other?
The ability of a material to transfer heat.
What is thermal conductivity?
This is the slowest way that heat travels.
What is conduction?
A measurement of the average kinetic energy of particles in an object.
What is temperature?
These are the things that bump into each other when a hot object touches a cold object, causing heat energy to transfer from one object to the other.
What are particles in the objects?
During convection, this explains what happens to the hot and cold particles.
What is the hot particles rise while the cold particles sink?
A material that conducts heat easily, or well.
What is a thermal conductor?
This is the fastest way that heat travels.
What is radiation?
The passing of heat through a material while the material itself stays in place.
What is conduction?
This device is used to measure average kinetic energy of the particles in a substance (a.k.a. temperature!)
What is a thermometer?
Convection happens in these types of substances.
What is a liquid or a gas?
A material that conducts heat poorly.
What is a thermal insulator?
Because animal fur traps air, it is a good example of this.
What is an insulator?
The flow of thermal energy through a liquid or a gas, caused by hot parts rising and cool parts sinking.
What is convection?
Radiation is the transfer of energy through these kinds of rays.
What are electromagnetic waves?
What is empty space?
Which type of substance is the worst heat conductor, or the BEST insulator?
What are gasses?
When energy is lost due to friction, it changes to thermal energy. In this instance, heat is considered to be this.
What is a waste product?
The transfer of energy through electromagnetic rays.
What is radiation?
The invisible electromagnetic rays that are produced by hot objects.
What are infrared rays?
A cook uses these kinds of rays in an oven to broil food, or heat the surface of the food quickly.
What are infrared rays?
The rate at which a substance changes temperature - some high and some low.
What is heat capacity?
This is the most common waste product that is produced from work.
What is heat?
