TEMPERATURE
UNIT: Kelvin (K), Centigrade or Celsius (C), Fahrenheit (F) and the fourth that is rarely used is Rankine (R)
DESCRIPTION: Temperature describes the average kinetic energy of molecules within a material or system.
MEASUREMENT: Temperature is measured with thermometers. Common thermometers consist of a glass rod with a very thin tube in it.
HEAT
UNIT: joules (J)
DESCRIPTION: Heat describes the transfer of thermal energy between molecules within a system.
MEASUREMENT: Measurement of heat is done in calories. One calorie is the amount of energy required to raise one gram of water one degree Celsius. To measure heat, you divide the change in temperature of a sample of water by the mass of the water.
