Heat I
A measurement of the average kinetic energy of the particles in an object.
Temperature.
The passing of heat through a material while the material itself stays in place.
Conduction.
Heat is ________________.
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 both have the same _____________.
temperature.
Infrared cameras can see ___________ and __________ things.
hot / cold.
The more __________________ an object contains, the more heat energy it has.
Molecules.
Materials that are not a good conductor of heat are called ___________.
Thermal Insulators.
Heat is 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: Heat 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.
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!)
Earth's surface is warmed by radiation from this.
The Sun.
How easily heat moves through a material.
Conductivity.
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.
Metals.
Materials with a low _______ ________ change temperatures quickly.
heat capacity.
