Which one of the following statements is correct when saturation press...
Explanation:
When the saturation pressure of a vapor increases, there are changes in various thermodynamic properties. The correct statement among the given options is:
b) Enthalpy of evaporation decreases
Enthalpy of evaporation:
Enthalpy of evaporation, also known as latent heat of vaporization, is the amount of energy required to change a given amount of liquid into vapor at a constant temperature. It is a thermodynamic property that depends on the pressure and temperature of the system.
Effect of saturation pressure on enthalpy of evaporation:
When the saturation pressure of a vapor increases, the enthalpy of evaporation decreases. This is because the energy required to change the liquid into vapor decreases as the pressure increases.
The following are the effects of saturation pressure on various thermodynamic properties:
Saturation temperature:
Saturation temperature is the temperature at which a given substance changes from a liquid state to a vapor state at a constant pressure. When the saturation pressure of a vapor increases, the saturation temperature also increases. This is because the pressure and temperature of a vapor are directly proportional.
Enthalpy of evaporation:
As explained earlier, the enthalpy of evaporation decreases when the saturation pressure of a vapor increases.
Specific volume change of phase:
The specific volume change of phase is the change in volume of a substance during a phase change. When the saturation pressure of a vapor increases, the specific volume change of phase also increases. This is because the volume occupied by a vapor increases as the pressure increases.
Conclusion:
When the saturation pressure of a vapor increases, the enthalpy of evaporation decreases. This is because the energy required to change the liquid into vapor decreases as the pressure increases.
