Test: Equilibrium in Physical Processes(July 11) - Question 1

### At what temperature does water and water vapor reach equilibrium at atmospheric pressure?

Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 1
Water and water vapor reach equilibrium at 100°C at atmospheric pressure (1.013 bar). This is known as the normal boiling point of water.
Test: Equilibrium in Physical Processes(July 11) - Question 2

### What is the condition for a system to be in equilibrium?

Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 2
In equilibrium, the key characteristic is that the temperature remains constant, as mentioned in the text. This is true for systems undergoing phase transformations, such as solid-liquid equilibrium, liquid-vapour equilibrium, and solid-vapour equilibrium.

Test: Equilibrium in Physical Processes(July 11) - Question 3

### What is the equilibrium condition for a system in Solid-Liquid Equilibrium?

Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 3
In Solid-Liquid Equilibrium, the temperature remains constant, indicating that the system is in equilibrium. This is also known as the normal melting point.
Test: Equilibrium in Physical Processes(July 11) - Question 4
What is the equilibrium condition in Liquid-Vapour Equilibrium?
Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 4
In Liquid-Vapour Equilibrium, the rate of evaporation is equal to the rate of condensation, which signifies equilibrium. Initially, the rate of evaporation is higher, but it decreases with time as condensation occurs.
Test: Equilibrium in Physical Processes(July 11) - Question 5
Which process involves the phase transformation of solid to vapor?
Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 5
Solid-Vapour Equilibrium involves the transformation of a solid into vapor, as seen in examples like solid iodine subliming to give iodine vapor.
Test: Equilibrium in Physical Processes(July 11) - Question 6
What is the equilibrium condition for a liquid at one atmospheric pressure?
Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 6
At one atmospheric pressure (1.013 bar), the equilibrium condition for a liquid is that its boiling point is 100°C. This is known as the normal boiling point of the liquid.
Test: Equilibrium in Physical Processes(July 11) - Question 7
What happens to the rate of condensation in Liquid-Vapour Equilibrium over time?
Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 7
In Liquid-Vapour Equilibrium, the rate of condensation decreases with time as the system approaches equilibrium. Initially, the rate of evaporation exceeds condensation, but they become equal at equilibrium.
Test: Equilibrium in Physical Processes(July 11) - Question 8
Which of the following substances exhibits Solid-Liquid Equilibrium at the normal melting point?
Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 8
Water exhibits Solid-Liquid Equilibrium at its normal melting point (0°C or 273K), as mentioned in the text. This is when ice and water coexist in equilibrium.
Test: Equilibrium in Physical Processes(July 11) - Question 9
In what type of system is it not possible to reach equilibrium?
Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 9
In an open system, it is not possible to reach equilibrium because molecules can disperse into the surroundings, making it challenging to achieve a balance between the rates of evaporation and condensation.
Test: Equilibrium in Physical Processes(July 11) - Question 10
What is the key factor that determines the boiling point of a liquid?
Detailed Solution for Test: Equilibrium in Physical Processes(July 11) - Question 10
The boiling point of a liquid depends on the atmospheric pressure. Different liquids have different boiling points at the same pressure.
