Question 1

Clapeyron’s equation is used for finding out the

Question 2

For air at a given temperature, as the relative humidity is increased isothermally,

Question 3

Using the Clausius–Clapeyron equation find the enthalpy of vaporization(in kJ/kg). The following data is given: At 200°C, v_g=0.1275 m³/kg and V_f= 0.001157 m³/kg and change of pressure with respect to temperature $Description: Description: 02_Thermodynamics_BLok_files\image035.png$ .

Question 4

Consider the Carnot cycle shown. In this 0.5 moles of an ideal monoatomic gas is given for T₁ = 500 K, V₂ = 2V₁ and V₃ = 1.5V₂. What will be the numerical values for

Question 5

The weight placed on the steam exhaust port of a domestic pressure cooker never allows the pressure to build up above 250 KPa inside the cooker. The latent heat of vaporization of water is 2257 kJ/Kg at 100 °C and 101.325 KPa. The temperature ( °C) at which water boils in the cooker is

Question 6

F or water at 23℃, dp_s⁄dT_s = 0.189 kPa⁄K (p_s is the saturation pressure in kPa and T_s is the saturation temperature in K) and the specific volume of dry saturated vapour is 43.38 m³/kg. Assume that the specific volume of liquid is negligible in comparison with that of vapour. Using the Clausius-Clapeyron equation, an estimate of the enthalpy of evaporation of water at 23℃(in kJ/kg) is __________
