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\(10^{5}J\)
E
3.3x\(10^{7}J\)
Verified Correct Answer: D.
Physical Principles & Numerical Solution
\(\Delta{H}=mL=0.1\times2.3\times10^6=2.3\times10^5\)J
