10.0 g of fuel are burned under a calorimeter (container that measures energy flow) containing 200 g of water. the temperature of the water increases from 15.0oc to 55.0oc. calculate the amount of heat released by the fuel per 1 gram of the fuel.

Answer : The amount of heat released by the fuel per 1 gram of the fuel is 3344 J.

Explanation :

Heat released by the fuel = Heat absorbed by the water

Formula used :

or,

where,

Q = heat absorbed = ?

m = mass of water = 200 g

c = specific heat of water =

= initial temperature  =

= final temperature  =

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

Thus, the heat absorbed by the water is 33440 J.

As, Heat released by the fuel = Heat absorbed by the water = 33440 J

Now we have to calculate the amount of heat released by the fuel per 1 gram of the fuel.

As, 10.0 grams of fuel released heat = 33440 J

So, 1 grams of fuel released heat =

Hence, the amount of heat released by the fuel per 1 gram of the fuel is 3344 J.
