Physical properties can be measured

Assertion : Heat added to a system at lower temperature causes greater randomness than when the same quantity of heat is added to it at higher temperature. Reason : Entropy is a measure of the degree of randomness or disorder in the system.

In an isothermal thermodynamical process, the value of work done by a system is

In which thermodynamic process the temperature of the system decreases ?

The thermodynamic property that measures the extent of molecular disorder is called entropy. Entropy change of phase transformation can be calculated using Trouton's formula (DeltaS = DeltaH//T) . In the reversible adiabatic process, however, DeltaS will be zero. the rise in temperature in isobaric and isochoric conditions is found to increase the randomness or entropy of the system. DeltaS = 2.303 C log (T_(1)//T_(2)) If water in an insulated vessel at -10^(@)C suddenly freezes, the entropy change of the system will be
