Question

For a two-component system, the degree of freedom is given by:

• A. \( F = 1 - P \)
• B. \( F = 2 - P \)
• C. \( F = 3 - P \)
• D. \( F = 4 - P \)

Hint:

In thermodynamics, the degree of freedom is used to calculate the number of independent variables in a system.

Answer 1

The Correct Option is A

Step 1: Determine the degree of freedom.
For a two-component system, the degree of freedom (\( F \)) is calculated using the formula: \[F = C - P\]where \( C \) represents the number of components and \( P \) represents the number of phases. Given that the system has two components, \( C = 2 \). Therefore, the formula simplifies to:\[F = 2 - P\]

Step 2: Finalize the result.
The calculated degree of freedom for the system is \( F = 2 - P \), which matches option (2).
