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 ... WebThe skeletal mode contribution to the molar heat capacity can be calculated with the Tarasov equation. For polystyrene this function reads: C T = 6 R [(T/42.5) 2 / (1 + (T/42.5) …

Polystyrene (PS) /ˌpɒliˈstaɪriːn/ is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of i… Webpolystyrene (amorphous): 1.04 – 1.065* PMMA: 1.195 (0ºC); 1.190 (20ºC); 1.188 (25ºC); 1.150 (T. g)*-glass transition temperature (T. g) polystyrene: 80-90ºC* PMMA: 377-378 K …
