Ask Me Help Desk - Find the equilibrium temp of the following

The heat absorbed by the glass and water must equal the heat given up by the alcohol as it all comes to equilibrium temperature. If the final temperature rise of the water and glass is $\Delta T$ , then the temperature drop of the alcohol is $25 - \Delta T$ . So you have:

$<br /> (350 g \times C_{glass} \ + \ 500g \times C_{water}) \Delta T = 400g \times C_{alcohol} \times (25 - \Delta T )<br />$

Presumably you have values for the various specific heats of each of these substances - solve for $\Delta T$ . Then the final temp is $10 + \Delta T$ .
