Answer:

39.1 °C

Explanation:

Recall the equation for specific heat:

[tex]q=mc \Delta T\\[/tex]

Where q is the heat, m is the mass, c is the specific heat of the substance (in this case water), and delta T is the change in temperature.

You should know that the specific heat of water is 1 cal/g/C.

Using the information in the question:

[tex]2035=500(1)(T-35)\\2035=500T-17500\\500T=19535\\T=39.07[/tex]

The final temperature is about 39.1 °C.
