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.

your answer would be “dry”

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
