Thermal energy can be ____________ from one object to another by __________, conduction, and convection |
transferred. radiation |
|
|
all objects, even ice cubes, radiate _________ energy |
thermal |
|
|
the only way for thermal energy to travel from the ______ to Earth is through radiation, that is because radiation is the only way for thermal energy to travel through the ________ or empty space |

|
|
_______ occurs in solids, liquids, and gases |
radiation |
|
|
when particles that have different kinetic energies ___________, the particles that have _________ kinetic energy transfer energy to particles that have __________ kinetic energy, in this way the average kinetic energy or __________ of the materials change |
collide. more. less. temperature |
|
|
because kinetic energy is being transferred, __________ energy is also being transferred |
mechanical |
|
|
_________ is the transfer of thermal energy between materials because of collisions between the particles |
conduction |
|
|
conduction does not stop until the ________ energy of all the particles that are in contact is ___________ |
thermal. equal |
|
|
a material through which thermal energy flows easily is called a _______________, a material through which thermal energy does not flow easily is called a ____________ |
thermal conductor. thermal insulator |
|
|
____________ are good thermal conductors because they have _________ that move easily, so they often collide with other particles and transfer _________ energy easily |
metals. electrons. kinetic energy |
|
|
_________ are good thermal insulators because their electrons do not ________ easily, so compared with thermal conductors few __________ occur between electrons and atoms of insulators |
nonmetals. move. collisions |

|
water has a __________ specific heat, which have a low ____________ |
high. cooling |
|
|
an increase in a materials volume when the temperature is increased is called _______, this occurs because _________ get closer together as their kinetic energy decreases |

|
|
the transfer of thermal energy by the movement of particles from one part of a material to another is called ___________, convection occurs in _____________ liquids and gases |
convection. fluids |
|
|
convection occurs, in part, because of differences in _____________ due to thermal _____________ and thermal contraction in different parts of the material |
density. expansion |
|
|
the movement of fluids up and down in a cycle because of convection is called __________, these ________ use patterns in Earth's climate |
convection current, currents |
