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.

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

i'm wiling to try and you : )
