Temperature.
Heat through a materials that are touching
Conduction.
Heat is ________________.
Transfer of thermal energy
Heat is ___________________ flowing from a warmer object to a cooler one.
Thermal Energy.
Heat continues to flow from one object to another object until they reach _________.
thermal equilibrium

hot / cold.
The more __________________ an object contains, the more thermal energy it has.
Particles, Atoms
Materials that are not a good conductor of heat are called ___________.
Thermal Insulators.
Heat is thermal energy that moves from an object with a ___________ temperature to an object with a _______ temperature.
higher / lower.
Heat is the ______________ amount of thermal energy that an object releases.
total
The flow of thermal energy through a liquid or a gas, caused by hot parts rising and cool parts sinking.
Convection.
Three ways in which heat is transfered.
Conduction, convection, radiation.
True or False: Thermal energy can keep things warm, do work, and make engines run.
True.
Heat traveling by conduction moves at the speed at which molecules can ________ one another and change how fast nearby molecules are vibrating.
Bump, Hit, Run into, Collide
Which has a higher heat capacity - sand or water?
Water.
Thermal energy that flows between objects due to a difference in temperature.
Heat.
________________ is not needed to transmit radiation.
Matter. (Electromagnetic rays can travel through empty space - otherwise, heat from the Sun could not warm Earth!)

Specific Heat
The ability of a material to transfer heat.
Thermal Conductivity.
Transfers heat in radition.
Electromagnetic rays.
Responsible for winds on Earth.
Convection currents.
Kinds of matter that conduct heat faster than others, makes up a large portion of the periodic table.
Metals.
Materials with a ____ specific heat change temperatures quickly.
