The amount of maximum mass of ethyl alcohol that could we boil with 1000 J of heat, starting from 20°C is 7.08 grams.

How do we calculate the mass?

Mass of the ethyl alcohol will be calculated by using the below equation as:

Q = mcΔT, where

  • Q = absorbed heat = 1000 J
  • m = mass of ethyl alcohol = ?
  • c = specific heat of ethyl alcohol = 2.42 J/g.°C
  • ΔT = change in temperature = (78.37°C - 20°C) = 58.37°C

On putting all these values, we get

m = 1000 / (2.42)(58.37) = 7.079 = 7.08g

Hence required mass of ethyl alcohol is 7.08grams.
