**__ENERGY CONVERSION FACTORS__**
__** 1 calorie (cal)=4.184 joules (J) 1 Calorie (Cal)=1000 calories (cal) 1 kilowatt-hour (kWh)=3.60 x 10^6 joules (J)

is releasing energy VS. absorbing energy
 * Exothermic VS. Endothermic

**__Temperature__**
K=C+273 C=F- 32 divided by 1.8

//*be able to convert between temps*//

__**Temperature Changes: Heat Capacity:**__ Heat= mass x specific heat capacity x the temperature change q=mcdelta t //REMEMBER THE SPECIFIC HEAT CAPACITY OF WATER IS 4.184!!!// ** //*be able to manipulate this equation to solve for any variable given, remember to incorporate sig figs*//
 * Heat capacity**: is the quantity of thermal energy (usually in joules) required to change the temperature of a give amount of the substance by 1 degree celsius.
