The first law of
The equation for the first law of thermodynamics can be given as,
Here
(a)

Explanation of Solution
Given,
A
The final temperature of the sample can be calculated as follows,
The volume of the substance will change in accordance to the piston’s movement.
Thus,
According to the Ideal gas equation,
At equilibrium the volume is
Therefore,
First law of thermodynamics can be written as,
Substituting the known values in the above equation,
Therefore, final temperature (
(b)
Interpretation:
Concept Introduction:
Specific heat:
Specific heat can be defined as quantity of heat required to raise the temperature of
Where
c= Specific heat
The first law of thermodynamics states that energy can be either destroyed or created but instead it can be converted from one form to other.
The equation for the first law of thermodynamics can be given as,
Here
(b)

Explanation of Solution
A
At equilibrium the volume is
Therefore,
