simple harmonic motion- a particle that is disturved awat from its fixed equilibrium position experiences an acceleration that is proportional and opposite to its displacement
heat
placed in ice and boiling water. boiling being 100 ice being 0. equal intervals placed between
heat
heat is ebergy that is exchanged between systems at different temperatures
internal energy
the total kinetic energy of the molecules of a system plus the potential energy associated with the intermolecular forces
absolute temperature
the absolute temperature of a gas is a measure of the average kinetic energy of its molecules
mole
the amount of substance that contains as meant elementart particles (atoms, ions, molecules) as there are in 12g of carbon-12 atoms
avogadros constant
6.022*10^23 mol^-1
specific heat capacity
the heat required to raise unit mass of a substance by unit temperature interval under specified conditions, such as constant pressure: usually measured in joules per kelvin per kilogram. Symbol cp (for constant pressure) Also called specific heat
Q=mc(delta)T
specific latent heats of fusion
The amount of heat released / absorbed from a substance at constant temperature as you change state from liquid->solid / solid->liquid.Read more:
vaporization
the transition of matter from a solid or liquid phase into a gaseous (or vapor) phase. Water boiling into steam is an example of vaporization
why does temperature stay constant during a phase change
Because the energy is all being used to change the state of the substance (ordering the molcules) instead of increasing the temperature ("jiggling" the molecules.
