A swimmer coming out from a pool is covered with a film of water weighing about 18g. How much heat must be supplied to evaporate this water at 298 K? Also calculate the internal energy of vaporisation at 298K. (∆ vap H ⊖ for water at 298K= 44.01kJ mol –1 )

Options

  1. AHeat supplied is 56.47 kJ and ∆ vap U v is 50.03 kJ
  2. BHeat supplied is 48.53 kJ and ∆ vap U v is 44.01 kJ
  3. CHeat supplied is 50.03 kJ and ∆ vap U v is 56.47 kJ
  4. DHeat supplied is 44.01 kJ and ∆ vap U v is 41.53 kJ

Correct answer

D. Heat supplied is 44.01 kJ and ∆ vap U v is 41.53 kJ

Step-by-step solution

Correct Option is : (D) Heat supplied is 44.01 kJ and ∆ vap U v is 41.53 kJ
