Answer:

2441.9 Joules

Explanation:

This is a sensible heat change problem.

Energy = Specific Heat Capacity x Mass x Change in Temperature

To find the change in temperature, you need to use this formula: Temperature Final - Temperature Initial.

234.3 - 137.0 = 97.3

Energy = 1.65 x 15.21 x 97.3

Multiply that equation, and you get your answer! I hope this helps!
