related to the random motion of atoms and molecules in a substance. measure of the average translational kinetic energy per molecule in a substance. measured in degrees.
the energy transfer from one object to another because of a temperature difference. measured in joules
grand total of all energies inside a substance. rotational kinetic energy, kinetic energy, potential energy.
the amount of heat required to change the temperature of 1 gram of water by 1 Celsius degree.
Specific Heat Capacity
quantity of heat required to change the temperature of a unit mass of the substance by 1 degree.
when temperature of a substance is increased, its molecules or atoms jiggle faster and move further apart resulting in the expansion of the substance.
the lowest possible temperature that a substance may have- the temperature at which molecules of the substance have their minimum kinetic energy.
the transfer of heat energy by molecular and electron collisions within a substance. especially a solid.
the transfer of heat energy in a gas or liquid by means of currents in the heater fluid. the fluid moves, carrying energy with it.
Newtons Law of Cooling
the rate of loss of heat from an object proportional to the temperature difference between the object and its surroundings.
the time in which a vibration is completed. the period of a wave equals the period of the source, and is equal to 1/frequency.
a stationary wave pattern formed in medium when two sets of identical waves pass through the medium in opposite directions.
a frequency at which an elastic object naturally tends to vibrate if it is disturbed and the disturbing force is removed.
a result of superposing different waves, often of the same wavelength. constructive interference results from crest to crest reinforcement; destructive interference results from crest to trough cancellation.
a series of alternative reinforcements and cancellations produced by the interference of two waves of slightly different frequencies, heard as a throbbing effect in sound waves.
What is most closely related to the average kinetic energy of translational motion of the molecules in an object?
the temperature of the object
How much heat ( in "calories" ) would it take to change the temperature of 3 grams of the water ( liquid ) from 0 degrees C to 4 degrees C?
