Temperature
The Kelvin temperature of absolute zero
0 K
When ice is melting, what is the Celsius temperature
0 C
these are poor at transferring heat
insulators
what happens to the temperature of cold water after a cube of hot metal is placed in the water
temperature increases
This type of heat transfer occurs by way of heat moving through a fluid
convection
freezing temperature of water on Celsius scale
0 C
to change ice to water, is the ice heated or cooled?
heated
the sum of both the kinetic and potential energies of a substance
internal energy
as heat moves from a hotter to colder substance, what happens to the kinetic energy of the hotter substance losing heat
decreases
the method by which sunlight delivers heat
radiation
boiling temperature of water on Celsius scale
100 C
what is the change of state when something freezes
liquid to solid
energy needed to raise 1 g of water 1 degree Celsius
calorie
this determines the direction in which heat will flow
change in temperature
heat is the transfer of this type of energy
thermal energy
convert from Celsius to Kelvin
add 273
during which state do the molecules have the most kinetic energy
gas
the unit for thermal energy
joule
what happens to the temperature of 2 substances of different temperatures after being mixed and allowing time to pass
they eventually will have the same temperature
the amount of heat needed to raise one kilogram of a substance by one degree Celsius
specific heat
temperature measures this
average kinetic energy of molecules of a substance
how does the temperature respond while water is boiling
temperature does not change
substances, usually metals, that easily transfer heat
conductors
if two objects come into contact and there is no change in temperature, why
they had the same temperature at the beginning
the method by which heat is transferred between touching objects
conduction
