Question

Calculate the heat created by the food if the mass if the water is 100 g, the specific heat of water is 4.18 J/g°C and the change of temperature is 9.5 °C. A.) 1395 B.)2495 C.)3095 D.) 4478

Answer 1

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

Explanation :

Formula used:

`q=m* c* \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* 4.18J/g^oC* 9.5^oC`

`q=3971J`

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