A 32 g ice cube at its melting pointis dropped into an insulatedcontainer of liquid nitrogen. How muchnitrogen evaporates if it isat its boiling point of 77 K and has alatent heat of vaporizationof 200 kJ/kg? Assume for simplicitythat the specific heat of ice isa constant and is equal to itsvalue near its melting point.
