Boiling point is a temperature at which vapour pressure of liquid is equal to the atmospheric pressure around it. When we increase the temperature, the molecules of liquid move away from each other due to expansion. And this is why boiling point of a liquid increases with increase in temperature.

Based on the statements given here choose the correct answer.(1) Boili...
Explanation:
Both statements 1 and 2 are true, and statement 2 explains statement 1.
Explanation of Statement 1:
When a liquid is heated, it gains energy, and the molecules in the liquid gain kinetic energy. As a result, the molecules move faster and farther apart, which reduces the attractive forces between them. As the temperature of the liquid increases, the vapor pressure of the liquid also increases. When the vapor pressure of the liquid becomes equal to the atmospheric pressure, bubbles start forming in the liquid, and the liquid starts boiling. Thus, the boiling point of a liquid increases with an increase in temperature.
Explanation of Statement 2:
The vaporisation curve shows the variation of the boiling point of a liquid with pressure. When a liquid is heated, its vapor pressure increases, and at a certain pressure, the vapor pressure of the liquid becomes equal to the atmospheric pressure, and the liquid starts boiling. The boiling point of a liquid depends on the pressure of the surroundings. If the pressure is increased, the boiling point of the liquid also increases, and if the pressure is decreased, the boiling point of the liquid decreases. The volume of liquids increases on boiling because the molecules in the liquid gain energy and move farther apart. This results in an increase in the distance between the molecules and an increase in the volume of the liquid.
Therefore, both statements 1 and 2 are true, and statement 2 explains statement 1.
- Statement 1: Boiling point of a liquid increases with increase in temperature.
- Statement 2: The volume of liquids increases on boiling and the vaporisation curve shows the variation of the boiling point of a liquid with pressure and expands the equilibrium state between liquid and vapour phase.
Both statements 1 and 2 are true, and statement 2 explains statement 1.

If the pressure is increased, the boiling point of the liquid also increases, and if the pressure is decreased, the boiling point of the liquid decreases. The volume of liquids increases on boiling because the molecules in the liquid gain energy and move farther apart.
