Answer to Question #186098 in Chemistry for ssds

Question

An 11.25 g ethanol is heated from 25 degree C to 52.1 degree C. Calculate the amount of heat absorbed by the ethanol.

Answer 1

According to the heat equation:

Q = cm(T₂-T₁)

where Q - absorbed heat, c - specific heat (2.44 J/gºC), m - mass, T₂ - final temperature, T₁ - initial temperature.

From here:

Q(ethanol) = cm(T₂-T₁) = 2.44 J/gºC × 11.25 g × (52.1ºC - 25ºC) = 744 J

Answer: 744 J
