Question 1 Report

Calculate the quantity of heat released when 100g of steam at 100°C condenses to water(Take the specific latent heat of vaporization of water as 2.3x \(10^6Jkg^{-1}\))
Answer Details
When steam at 100°C condenses to water, it releases energy in the form of heat. The heat released is equal to the product of the mass of the steam and the specific latent heat of vaporization of water. Given, mass of steam = 100g = 0.1 kg Specific latent heat of vaporization of water = 2.3 x 10^6 J/kg Therefore, the quantity of heat released when 100g of steam at 100°C condenses to water can be calculated as: Q = m × L = 0.1 kg × 2.3 × 10^6 J/kg = 2.3 × 10^5 J So, the correct option is: 2.3x\(10^{5}J\)
