Question

Calculate the heat energy that will be released when 5.0 kg of steam at 100°C condenses to form water at 100°C. Express your answer in S.I. unit. (Specific latent heat of vaporization of steam is 2268 kj/kg.)

Answer 1

Heat released by 5 kg of steam at 100°C to convert into water at 100°C. = mL
= 5 × 2268 KJ = 11440 kj.
