Heat Capacity And Specific Heat
Thermodynamics of Class 11
The heat capacity (C) of a sample of a substance is the quantity of heat needed to raise the temperature of the sample of substance one degree Celsius (or Kelvin).
q = cΔt
Heat capacity is directly proportional to the amount of substance.
The specific heat capacity is the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius at constant pressure.
q = s ×m × Δt
where q is the heat required to raise temperature
m = mass in grams
s = specific heat of the substance
Δt = temperature difference
