Calculate the heat energy required to vapor..

Question 1 Report

Calculate the heat energy required to vaporize 50g of water initially at 80ºC if the specific heat capacity of water is 4.23jg $^{- 1}$ k $^{- 1}$ (specific latent heat of vaporization of water is 2260jg $^{- 1}$

530000J

23200J

17200J

130000J

Answer Details

H = mc $△ θ$ + mL

H = ?

m = 50g, c = 4.23J/gk,L = 2260, $△ θ$ = 80ºC

H = 50 [4.23 x 80 + 2260]

= 129920 $\approx$ 130,000J
