Question

Calculate the amount of heat (in kJ) required to raise the temperature of a 65g sample of ethanol from -34°C to 30°C. The specific heat capacity of ethanol is 2.42 J/g°C.

Answer 1

Amount of heat (J) ta=mc AT & change in temperature (I final - Tinitial ) (°C) Specific heat (g) Capacity (519°c) mass Here we have - m = 65 g AT = Tf - Ti = 30°C - (-34°c) = 6uc c=2.42Jlg'c plugging values - a = 65 g x 2.42 I x 64°C 9°C a = 10067.2 J 25 { 19=600x3} IJ = 0.001 KJ Y a = 10.07 KJ Please Rate ...
