Answer:
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
