The molar heat capacity of water at constant pressure,CP, is75JK−1mol−1. When1.0kJof heat is supplied to100gof water which is free to expand, the increase in temperature of water is View Solution Free Ncert Solutions English Medium ...
The heat capacity at constant pressure of liquid water increases near the boiling temperature. The increase is more pronounced, the nearer the boiling temperature is to the critical temperature. Heat capacity of the gas exhibits the greatest deviations from ideal gas near the critical point. But ...
The measurements were taken in a high-temperature and high-pressure adiabatic nearly constant-volume calorimeter. Uncertainties of the isochoric heat capacity measurements are estimated to be less than 1.5 per cent. One- and two-phase heat capacities, temperatures, and densities at saturation were ...
The heat capacity at constant volume CV of pure water has been measured in the temperature range from 412 K to 693 K at 13 isochores between 250 kg·m-3 and 925 kg·m-3. Measurements cover the critical region and coexistence curve. Measurements have been made in both the one- and two...
The molar heat capacity of water at constant pressure, Cp is 75 J K−1mol−1. When 10 kJ of heat is supplied to 1 kg water which is free to expand, the increase in temperature of water is View Solution The molar heat capacity of water in equilibruim with ice at constant pressure...
Specific heat(Heat Capacity) is function of temperature and very weak function of pressure. Some literaures are avaiable for the specific heat values of water vapour at low temperature ranges you mentioned. I am just giving the values of specific heat of water vapour at constant pressure (Cp)...
