bulgar [2K]

Answer : The heat created by the food is, 3971 J

Explanation :

Formula used:

q=m\times c\times \Delta T

where,

q = heat produced = ?

m = mass of water = 100 g

c = specific heat capacity of water = 4.18J/g^oC

\Delta T = change in temperature = 9.5^oC

Now put all the given values in the above formula, we get:

q=100g\times 4.18J/g^oC\times 9.5^oC

q=3971J

Therefore, the heat created by the food is, 3971 J
