Answer:

[tex]\Delta T=0.160\°C[/tex]

Explanation:

Hello there!

In this case, according to the following equation for the calculation of heat in this calorimetry problem:

[tex]Q=mC\Delta T[/tex]

It is possible for us to calculate to calculate the change in temperature for this process by solving for DT in the aforementioned equation:

[tex]\Delta T=\frac{Q}{mC}\\\\ \Delta T=\frac{125.7cal}{634.5g*1.241 cal/(g\°C)} \\\\ \Delta T=0.160\°C[/tex]
