How much energy does it take to convert 10 g ether taken at the boiling point into steam?

Problem data: m (mass of taken ether) = 10 g (in SI m = 0.01 kg); ether has a boiling point.

Reference values: L (specific heat of vaporization of ether) = 0.4 * 10 ^ 6 J / kg.

The consumed thermal energy for vaporization of the taken ether is calculated by the formula: Q = L * m.

Calculation: Q = 0.4 * 10 ^ 6 * 0.01 = 4000 J (4 kJ).

Answer: For the vaporization of 10 g of ether, 4 kJ of energy was spent.
