If the temperature of 34.4g ethanol increases from 25.0 degrees c to 78.8 degrees c how much heat has been absorbed by the ethanol

Heat absorbed by ethanol is 4552.8 J.

Explanation:

Given data:

mass of ethanol = 34.4 g

Initial temperature = 25 °C

Final temperature = 78.8 °C

Heat absorbed by ethanol = ?

Solution:

specific heat capacity of ethanol = 2.46 j/g.°C

Change in temperature = 78.8°C - 25 °C = 53.8 °C

Formula

Q = m. c. ΔT

Q = 34.4 g × 2.46 j/g.°C × 53.8 °C

Q = 4552.8 J

c. is the answer
