The value of `(DeltaH- DeltaU)` for vaporisation of water at `100^@C` is 'x' x `10^2 J//"mole"`, assume water vapour to be an ideal gas [Take R = 8.31 `J//"mole".K`]

Determine the value of DeltaH and DeltaU for the reversible isothermal evaporation of 90.0g of water at 100^(@)C .Assume that water vapour behaves as an ideal gas and heat of evaporation of water is 540 calg^(-)R = 2.0 cal mol^(-1)K^(-1) .

What is value of DeltaU for reversible isothernal evaporation of 90g water at 100^(@)C ? Assuming water vapour behaves as an ideal gas, Delta_(vap. Water)H = 540cal g^(-1)

Determine the value of DeltaH and DeltaU for the reversible isothermal evaporation of 90.0g of water at 100^(@)C . Assume that water behaves as an ideal gas and heat of evaporation of water is 540 cal g^(-1) (R = 2.0 cal mol^(-1)K^(-1)) .

What is the value of DeltaE (heat change at constant volume)for reversible isothermal evaporation of 90g water at 100^(@)C Assuming water vapour behaves as an ideal gas and (DeltaH_("vap"))_("water")=540calg^(-1)

If water vapour is assumed to be a perfect gas, molar enthalpy change for vaporisation of 1 mol of water at 1 bar and 100^(@)C is 41 kJ mol^(-1) .Calculate the internal energy change, when (a) 1 mol of water is vaporised at 1 bar pressure and 100^(@) C. (b) 1 mol of water is converted into ice.
