In the psychrometric chart, what is/are different properties that is/are present?
Physical and thermal properties
This law states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
Third law – states that the entropy of a perfect crystal is zero at the absolute zero of
temperature.
also known as the Conservation of Energy principle, states that energy can
neither be created not destroyed, it can only change forms.
First Law –
deals with the quality of energy (energy degradation). There are two
classical statements of this law:
Kelvin-Planck statement: It is impossible to construct a device that will operate in a
cycle and produce no effect other than the raising of a weight and the exchange of
heat with a single reservoir.
Clausius statement: It is impossible to construct a device that operates in a cycle and
produces no effect other than the transfer of heat from a cooler-body to a hotter body.
Second Law
when two bodies have equality of temperature with a third body, they in turn
have equality of temperature with each other.
Zeroth law
