Calorimetry

  • Specific Heat: Amount of heat(Energy) required to raise the temp of 1 g of a substance by 1°C. Unit is J/g°C.
  • Heat lost/gained by a substance in a process is
    q=mCΔT
    m is mass in grams
    C is Heat Capacity of the substance
    ΔT is the Temperature Change experienced by the substance.
  • Constant Pressure Calorimetry: Heat lost/gained by one substance equals heat gained/lost by other substance. One of the substances is usually water:
    q1 = −q2
  • Constant Volume Calorimetry: Mass and Heat Capacity are combined into a single Heat Capacity for the apparatus, Cm, so the equation becomes:
    q = CmΔT
