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:

<u>Answer</u>:
If beaker tongs are not available, we could use crucible tongs to handle the hot beaker
<u>Explanation</u>:
Crucible tongs is tool shaped like a scissor where instead of two blades, two pincers or pieces of metals that concave together is used. They help us to hold or grasp a hot beakers, flasks or even small beakers. It is difficult for the people to catch or hold the hot beakers directly. So crucible tongs plays a vital role when burning, or using hot objects in the chemical laboratory.Crucible tongs are generally made with strong metal such as nickel, stainless or oxidized steel so as to withstand very high and extreme temperatures.
