How much heat is required to boil away 2.0 liter water that is at 100 $\circ$ C? ( L_v = 540 kcal/kg for water)

Question

Quizplus · Accepted Answer

To boil away 2.0 liters of water, we first convert the volume to mass, knowing that 1 liter of water has a mass of approximately 1 kg. Therefore, 2.0 liters of water have a mass of approximately 2.0 kg. The latent heat of vaporization for water is given as 540 kcal/kg. The heat required to boil away 2.0 kg of water is calculated by multiplying the mass of the water by the latent heat of vaporization: $2.0 \, \text{kg} \times 540 \, \text{kcal/kg} = 1080 \, \text{kcal}$.
