If the phase of a multi-component system is enlarged, which of the fol...
Explanation:
When the phase of a multi-component system is enlarged, several changes occur in the system. Let's examine each of the options to determine which one accurately describes these changes.
Option a) U, S, and V will increase, and T, p, and chemical potential will remain the same.
- Internal energy (U): The internal energy of a system is the sum of its kinetic and potential energies. When the phase of a system is enlarged, the internal energy generally increases due to an increase in the number of particles and their interactions. Therefore, U will increase.
- Entropy (S): Entropy is a measure of the disorder or randomness of a system. When the phase of a system is enlarged, the number of microstates (possible arrangements of particles) generally increases, leading to an increase in entropy. Therefore, S will increase.
- Volume (V): When the phase of a system is enlarged, the system occupies a larger volume. This can occur, for example, when a liquid evaporates to form a gas or when a solid melts into a liquid. Therefore, V will increase.
- Temperature (T): The temperature of a system is a measure of the average kinetic energy of its particles. When the phase of a system is enlarged, the temperature generally remains the same unless heat is added or removed from the system. Therefore, T will remain the same.
- Pressure (p): The pressure of a system is the force exerted by the system per unit area. When the phase of a system is enlarged, the pressure generally remains the same unless the volume changes significantly or external forces are applied. Therefore, p will remain the same.
- Chemical potential: The chemical potential of a component in a system is a measure of its potential to undergo a chemical reaction or phase change. When the phase of a system is enlarged, the chemical potential generally remains the same unless there are changes in the composition, temperature, or pressure of the system. Therefore, the chemical potential will remain the same.
Based on the explanations above, option a) accurately describes the changes that occur when the phase of a multi-component system is enlarged.
