  • Heat Capacity
    Amount of heat needed to change the temperature of a substance, measured in joules per degree Celsius or Kelvin.
  • Specific Heat Capacity
    Amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius or Kelvin.
  • Molar Heat Capacity
    Amount of heat needed to raise the temperature of 1 mole of a substance by 1 degree Celsius or Kelvin.
  • q
    Symbol representing the quantity of heat absorbed or released during a temperature change.
  • Δt
    Symbol for the change in temperature, typically measured in degrees Celsius or Kelvin.
  • m
    Symbol representing the mass of a substance, usually measured in grams.
  • n
    Symbol representing the number of moles of a substance involved in a heat transfer process.
  • Joule
    SI unit of energy, commonly used to express the amount of heat transferred in thermal processes.
  • Degree Celsius
    Temperature scale unit used to measure thermal energy changes in chemistry calculations.
  • Kelvin
    Absolute temperature scale unit, often used in scientific heat capacity calculations.
  • q = mcΔt
    Formula relating heat absorbed or released to mass, specific heat capacity, and temperature change.
