For an ideal gas, C_(V)=(3)/(2)R . (a) What will be the change in internal energy (DeltaU) of 1 mole of an ideal gas if its temperature is increased by 4K at constant volume ? What would be DeltaU if the temperature of this gas is increased by the same amount of constant pressure? keeping pressure constant if the temperature of that same amount of gas is increased by 4K then what will be the change in internal energy (DeltaU) of that gas? (c) give reason for different values of DeltaU and DeltaH ?

Assuming that water vapour is an ideal gas, the internal energy change (DeltaU) when 1 mol of water is vaporised at 1 bar pressure and 100^(@)C , will be (Given: at 1 bar and 373 K, molar enthalpy of vaporisation of water is 41kJ*mol^(-1),R=8.3J*mol^(-1)*K^(-1) )-

Determine the change in enthalpy and internal energy when 1 mole of water completely vaporises at 100^(@)C and 1 atm pressure. [Latent heat of vaporisation of water=536 cal*g^(-1) ]

Statement I : In an isothermal process the whole heat energy supplied to the body is converted into internal energy. Statement II : According to the first law of thermodynamics Delta Q = Delta U + p Delta V .

Standard enthalpy of vaporisation, Delta_(vap)H^theta for water at 100^@C Is 40.66 kJ mol^-1 . The internal energy of vaporisation of water at 100^@C (in kJ mol^-1 )is (Assume water vapour to behave like an ideal gas).

The molar enthalpy of fusion and molar entropy of fusion for ice at 0^(@)C and 1 atm are 6.01 kJ*mol^(-1) and 22.0J*K^(-1)*mol^(-1) , respectively. Assuming DeltaH and DeltaS are independent of temperature, show that the melting of ice at 1 atm is not spontaneous, while the reverse process is spotantaneous.

Addition of non-volatile solute to a solvent always increases the colligative properties such as osmotic pressure. Delta P . Delta T_b and Delta T_f . All these colligative properties are directly proportional to molality if solutions are dilute. The increases in colligative properties on addition of non-volatile solute is due to increases in number of solute particles. For different aqueous solutions of 0.1 N NaCI, 0.1 N urea, 0.1 N Na_2SO_4 and 0.1 N Na_3PO_4 solution at 27^@C , the correct statements are : 1. The order of osmotic pressure is NaCI = Na_2SO_4 = Na_3PO_4 = urea 2. pi = (Delta T_b)/k_b xx RT for urea solution 3. Addition of salt on ice increases its melting point 4. Addition of salt on ice bring in melting of ice earlier
