PLS HELP I DONT GET THIS PROBLEM ...Using the above data table and graph, calculate the total energy in Joules required to raise the temperature of 15.0g of ice at -5.00ºC to steam at 35.0ºC

a) 7730 J
b) 7740 J
c) 7370 J
d) 7340 J

C. 7370 joules.

Explanation:

There is a mistake in the statement. Correct form is described below:

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.

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.
