An ideal gas undergoes isothermal compression from 5m³ to 1 m³ against a constant external pressure of 4 Nm^–2. Heat released in this process is used to increase the temperature of 1 mole of Al. If molar heat capacity of Al is 24 J mol^–1 K^–1, the temperature of Al increases by :

Elevation in the boiling point for 1 molar solution of glucose is 2 K. The depression in the freezing point for 2 molal solution of glucose in the same solvent is 2 K. The relation between K_b and K_f is
