if a hot 500mL bowl of soup was 88 degrees, then cooled down to 10 degrees, how much heat was lost?
Hint: not 88-10​

Answer:

163.02 kJ

Explanation:

Heat energy can be calculated using

Q=mcθ

where Q = Heat energy

           m =mass

           c = specific heat capacity

           θ =temperature difference

here we need the specific heat capacity and the density of the soup.

Assumptions

  • specific heat  be approximate to specific heat of water =4.18 J/g C
  • density = 1 g/cm3 (water)
  • 1 ml = 1 cm3
  • mass= volume * density

Q=mcθ

Q=(v*d)*cθ

Q = (500* 1) * 4.18 *(10-88)

Q = -163020 J

Q= 163.02 kJ
