Answer:

Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:

Substitue the values into the formula.

Multiply the first numbers together. The grams will cancel.

Multiply again, this time the degrees Celsius cancels.

<u>121.905 Joules</u> are required.
