Product description
7. Find the change in entropy g kg of a substance during heating (cooling) in the temperature range from T1 to T2, if its melting and boiling points, average heat capacities, heats of melting and evaporation are known. (Table 3)
2. Calculate what the changes in entropy, Gibbs energy, Helmholtz energy, internal energy, enthalpy and work of expansion are equal to if 1 mole of a substance whose vapor obeys the laws of ideal gases passes from a liquid to a vapor state at a normal boiling point.
