#### Answer:

I got

#### Explanation:

Let's get started by using the specific heat capacity equation:

Based on what you've given me, we have the mass of the sample (m), the specific heat (c), and the change in temperature

I should also add that "m" isn't limited to just water, it can be the mass of almost any substance. Also, **final temperature- initial temperature**

(

All of the variables have good units, so we just have to multiply all of the given values together to obtain Q (energy transferred).
