Calculate the amount of heat (in kJ)required to raise the temperature of a 79.0 g sample of ethanol from 298.0 K to 385.0 K.The specific heat capacity of ethanol is 2.42 J/g°C.

Question

Quizplus · Accepted Answer

The heat required can be calculated using the formula q = mcΔT. Here, m = 79.0 g, c = 2.42 J/g°C, and ΔT = 385.0 K - 298.0 K = 87.0°C. Converting the result from J to kJ gives q = 16.6 kJ.
