It would be 100.60 because we're adding like to the atmosphere it connects to lubricator and then it turns so that's 100.60
This problem is providing us with the mass (70 g), absorbed heat (96 J) and initial and final temperatures (293 K and 313 K, respectively) so the specific heat of the material is required and found to be 0.0686 J/(g*K) as shown below:
<h3>
Calorimetry:</h3>
In chemistry, we can go over calorimetry by writing the following relationship among heat, mass, specific heat and temperature change:

Thus, one can get the specific heat by solving for C in the previous equation:

Hence, we can plug in the given data to obtain:

It's a chemical change beacause elements are combining to make something new! :)
