1. Aim: How do chemists distinguish between HEAT and TEMPERATURE? Vocabulary: Heat- form of energy transferred from object of higher temperature to an object of lower temperature. Temperature- average kinetic energy of motion of particles in an object. (Think speed of particles!)

2. Aim: How do chemists distinguish between HEAT and TEMPERATURE? Is it possible that the cup of water and the water in the bath tub could have the same temperature? Explain. 25 o C 25 o C

3. Aim: How do chemists distinguish between HEAT and TEMPERATURE? Vocabulary: Specific heat capacity- amount of heat energy required to raise the temperature of 1g of a material by 1K (or C o.)

4. Aim: How do chemists distinguish between HEAT and TEMPERATURE? HEAT FORMULA- (Calorimetry) q=mC∆T * Refer to Table T q=heat (J) m=mass (g) C=specific heat capacity (J/g. K) ∆T=change in temperature (C o )

5. Aim: How do chemists distinguish between HEAT and TEMPERATURE? Essential Questions: Distinguish between heat and temperature. Why does your hand feel cold when you hold ice? Why does sand heat up so much more quickly than water? True or false: A change of 1 C° is equal to 1K. Explain.
