Answer:
C. 7370 joules.
Explanation:
There is a mistake in the statement. Correct form is described below:
<em>Using the above data table and graph, calculate the total energy in Joules required to raise the temperature of 15 grams of ice at -5.00 °C to water at 35 °C. </em>
The total energy needed to raise the temperature is the combination of latent and sensible heats, all measured in joules, and represented by the following model:
(1)
Where:
- Mass of the sample, in grams.
- Specific heat of ice, in joules per gram-degree Celsius.
- Specific heat of water, in joules per gram-degree Celsius.
- Latent heat of fusion, in joules per gram.
- Initial temperature of the sample, in degrees Celsius.
- Melting point of water, in degrees Celsius.
- Final temperature of water, in degrees Celsius.
- Total energy, in joules.
If we know that ,
,
,
,
,
and
, then the final energy to raise the temperature of the sample is:
Hence, the correct answer is C.
