NDA 2026 Physics question
An insulating container contains 250 g of water at 20°C. Steam at 100°C is passed through it, heating it up to 25°C. During this process, part of the steam also gets condensed, raising the mass of water to 252 g. If the specific heat of water is , then what is the value of the latent heat of steam ?
Answer: (C)
Solution
Mass of steam condensed . Heat gained by water $= 250 × 1 × (25 - 20) = 1250\
