Answer:
Step-by-step explanation:
According to the First Law of Thermodynamics, the heat received by the metal cylinder is equal to the change in the internal energy. That is:
The specific heat is clear in the previous expression and finally computed:
Answer:
The final pressure of the gas when its temperature returns to its initial value Pa.
Step-by-step explanation:
Given : An ideal gas is confined within a closed cylinder at a pressure of Pa by a piston. The piston moves until the volume of the gas is reduced to one-ninth of the initial volume.
To find : What is the final pressure of the gas when its temperature returns to its initial value?
Solution :
Since the temperature is constant .
The relation between P and V is given by,
....(1)
The piston moves until the volume of the gas is reduced to one-ninth of the initial volume i.e.
or
Substitute in equation (1),
The final pressure of the gas when its temperature returns to its initial value Pa.
