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
