Entropy
amount of disorder in a system
Calorimetry
process of measuring the thermal energy change in a chemical or physical change
Hess’s Law
total enthalpy change for the reaction is the sum of all enthalpy changes in the reaction
Thermodynamic Equilibrium
when two objects balance to the same final temp
le chatelier’s principle
states that if chemical equilibrium is disturbed by changes in reaction condition, the reaction will shift in the direction that counteracts the change.
specific heat capacity
amount of heat it takes for something to heat up
enthalpy
total amount of heat change
1st law of thermodynamics
energy can not be created or destoryed
Gibb’s Free energy
amount of energy available for the chemical reaction system to do work
Calorimeter
Allows us to measure thermal energy changes in a chemical or physical change
