since Ethanol has a heat capacity of 0.614 cal/g °C. If 50 g of ethanol has a temperature of 30ºC and a piece of hot Copper is added to the ethanol causing the temperature to increase to 70ºC. What is the amount of heat absorbed by the ethanol?

This question involves the concepts of heat capacity, temperature, and heat.

The heat absorbed by ethanol is "1228 cal".

HEAT CAPACITY

The heat capacity of a substance is defined as the amount of heat absorbed by a unit amount of that substance for a degree rise in temperature. Mathematically,

[tex]Q = mc\Delta T[/tex]

where,

  • c = heat capacity = 0.614 cal/g.°C
  • m = mass of ethanol = 50 g
  • ΔT = change in temperature = 70°C - 30°C = 40°C
  • Q = amount of heat absorbed = ?

Therefore,

Q = (50 g)(0.614 cal/g°C)(40° C)

Q = 1228 cal
