Physical Science Ch. 9 Test Review Crossword

heat transfer where thermal energy is carried from one location to another by a fluid
heat transfer where electromagnetic energy moves directly away from the source
energy that is the sum of all kinetic and potential energies in an object
point reached from the continual transfer of thermal energy between objects until they are the same temperature
Convection is the only type of heat transfer that can travel through a _?_ because it does not need matter to transfer.
Neither internal nor thermal energy can be directly _?_, only changes in them can be.
a fluid's resistance to flow; thickness
2nd best conductors of thermal energy (the best is too expensive to be practical)
amount of thermal energy that must be gained or lost to change the temperature of an object by 1°C
heat transfer where two objects of different temperatures come in direct contact with each other
A vacuum is the best _?_ because there are no particles that can transfer energy.
basic state of matter where particles have the most energy, making them good insulators because the particles spread far apart
energy that is the sum of all kinetic energies in an object
Insulators _?_ the flow of thermal energy.
Conduction is the main source of heat transfer in _?_.
Heat always transfers from _?_ to _?_.
a measure of the kinetic energy in a substance
term for the common points used on the Fahrenheit and Celsius scales
The anchor points for the Fahrenheit and Celsius scales are the same but their _?_ are different.
force needed for convection to occur (it pulls the dense fluids back down)
In containers holding fluids at the same temperature, the _?_ container will have more thermal energy.
When an object increases in length or volume as temperature increases, it is experiencing thermal _?_.
When power lines sag in the hot weather, the electrons become more disorganized and do not allow electricity to flow as easily, this is known as electrical _?_.
the flow of thermal energy form one object to another
