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 \(10^6Jkg^{-1}\))
- A. 2.3x\(10^{1}J\)
- B. 2.3x\(10^{2}J\)
- C. 2.3x\(10^{4}J\)
- D. 2.3x\(10^{5}J\)
Correct Answer: D. 2.3x\(10^{5}J\)
Explanation
\(\Delta{H}=mL=0.1\times2.3\times10^6=2.3\times10^5\)J
