Topic 6: Introduction to Matter and Energy
(Key Concepts)

*Energy, Heat, Temperature, Thermometers, Temperature Scales
Energy (E)= the ability to cause change or do work
Heat (H, q)= the sum total of the kinetic energies
Temperature (T)= the average kinetic energy
q = mHf (to find energy used to melt)
q = mHv (to find energy used to vaporize)
q = mCdeltaT (to find energy used to raise temp)



*Classification of Matter



*Separation of Mixtures
*Filtration: Separate insoluble substances like sand from water.



*Distillation: Separate substances based on different boiling points like petroleum or alcohol and water.

*Evaporation: Separate substances based on different boiling points like salt and water.
