The fuel released 90 calories of heat.
Let suppose that water experiments an entirely <em>sensible</em> heating. Hence, the heat released by the fuel is equal to the heat <em>absorbed</em> by the water because of principle of energy conservation. The heat <em>released</em> by the fuel is expressed by the following formula:
(1)
Where:
- - Mass of the sample, in grams.
- - Specific heat of water, in calories per gram-degree Celsius.
- - Temperature change, in degrees Celsius.
If we know that , and , then the heat released by the fuel is:
The fuel released 90 calories of heat.
