Laws Of Thermodynamics

Step 1: Define extensive and intensive properties. \textit{Extensive properties} depend on the amount of matter in the system.
\textit{Intensive properties} do not depend on the amount of matter in the system.
Step 2: Classify each property in the list. \begin{itemize} \item Mass: Extensive \item Temperature: Intensive \item Pressure: Intensive \item Enthalpy: Extensive \item Heat Capacity: Extensive \item Internal Energy: Extensive \item Density: Intensive \end{itemize}
Step 3: Count the number of extensive and intensive properties. Number of extensive properties = 4 (Mass, Enthalpy, Heat Capacity, Internal Energy) Number of intensive properties = 3 (Temperature, Pressure, Density) Final Answer:

The work done during an isothermal expansion is given by the equation: Where , and .
The work done is , so we have the equation: Solving for , we get .

Step 1: Identify the type of process and the relevant formula.
The process is an isothermal reversible expansion of an ideal gas. The heat absorbed ( ) by the system is equal to the work done by the system ( ):
$ for the initial state, we can also write:
\) L, atm, L.atm, L.
Substituting these values into the formula:
\) .
Divide both sides by 20: \) : \) $ Final Answer:
