  1. Define Heat.
    Also called thermal energy (symbolized by q) is the energy transferred as a result of a difference in temperature between the system and the surroundings.
  2. Define work.
    The energy transferred when an object is moved by a force.
  3. ⌂E=__?

    • D.
    • ⌂E=q+w
    • Change in energy is equal to the sum of energy transferred as heat and/or work.
  4. How many Joules are in a calorie?
  5. What is an equation which relates change of enthalpy and heat transferred?
    • qp=⌂E+P⌂V=⌂H
    • Heat transferred equals the sum of the change of energy with the PV work done by the system. 
    • These two equal the change of enthalpy.
  6. Define specific heat capacity.
    The quantity of heat required to change the temperature of 1 gram of the object by 1K
