Specific heat capacity of polystyrene
WebThe specific heat capacity (or just specific heat) is the heat capacity per gram of the reservoir liquid and is given the symbol, C. Thus the units for C are, J/g⋅°C or J/g⋅K. Since the heat capacity of a given mass of liquid can be written as C × (mass), Equation (1) becomes: qres = C × mass × ΔT (3) The specific heat of water has the ...
