# 150mL of water at 25oC is mixed 325mL of 80oC water in a sealed vacuum insulated vessel. Determine the final temp of the combined 475mL of water. The density of water is 1g/mL. What's the final temperature??

## I got 127.23 degrees celsius. Am I correct?

The final mix temp is ${64.7}^{o} C$. Note: Generally, for mixing two quantities of water at different temperatures, the final temperature will be between the initial temp and the final temp. Such is a good way to determine if your calculation is in the proper range.

#### Explanation:

Using Method of Mixtures $\implies {T}_{f \text{i} n a l} = {64.7}^{o} C$ see written explanation below.
