Question
Can you please help me find the specific heat of each metal. I am very confused on how to do it all. If you could show your work that would be helpful! Thank you.

Explanation / Answer
As per the given equation, we need to find cm....which the specific heat of metal....
In the formula delta T is Tfinal - Tinitial
Now, substitution of values in the table gives us
- 13.3 * (26-101)*cm = 25*(26-24)*4.186
Here 4.186 is standard specific heat of water
Now solving for cm we get
Cm = 209.3 / 997.5
Cm = 0.2098 J/g degree Celsius
In the same way you can find specific heat of other metals.
Now coming to questions
A) it reduces effect of environment outside the calorimeter
B) the work done in expansion includes energy which is very small and can be neglected
C) because filling is less dense and more heat is absorbed which makes it hotter
D) it is caused by conduction in which heat travels through the body. The metal is heated by boiling water. When this metal is placed in calorimeter, conduction causes temp to rise.
