Unformatted text preview: Particles are in continuous motion Energy transfers from collisions Exothermic Reaction: Reaction which releases energy (warm) Endothermic Reaction: Reaction that absorbs energy (cold) Activation Energy: Minimum amount of energy needed to start a reaction Specific Heat Capacity (Cp): Amount of heat energy needed to raise 1 gram of a substance 1C Joules (J): Heat energy (q) q = (m)( T)(Cp) Heat loss = Heat gain (m)( T)(Cp) = (m)( T)(Cp) (If the heat of the object decreases then its Initial Final and vice versa) Heat (enthalpy) of fusion: Amount of heat energy needed to melt a substance at its melting point q = (m)(H of F) Heat of Vaporization: Amount of heat needed to vaporize a substance at boiling point q = (m)(H of V) Triple Point: When all phases are at equilibrium...
