Thermodynamics Pt. 2: Chapter Eight

• the science of measuring heat changes (1) for chemical reactions. 
• two

measures heat change at constant volume such that q= DeltaE

measures heat change at constant pressure such that q= DeltaH

amount of heat required to raise the temperature of an object or substance a given amount

• amount of heat requried to raise hte temperature of 1.00 grams of the substance by 1.00 degress Celcius
• moles

amount of heat required to raise the temperature of one mole of a substance oby 1.00 degree celcius

overal enthalpy change for a reaction is equal to the sum of the enthapy changes for the individual steps in the reaction
