Question

Pick out the correct statements regarding the boiling point and the condensation point for a substance.

• A. Boiling point and condensation point are not the same.
• B. At boiling point, liquid changes into gas.
• C. During condensation, gas converts to a liquid.
• D. At condensation point, gas changes into liquid.

Answer 1

Answer: (B), (C), (D)

The correct options are
B At boiling point, liquid changes into gas.
C During condensation, gas converts to a liquid.
D At condensation point, gas changes into liquid.

The boiling point of a substance is the temperature at which the liquid state changes to the gaseous state for standard pressure.

The condensation point of a substance is the temperature at which the gaseous state changes to the liquid state for standard pressure.

For a given substance, boiling point and condensation point are identical.
