Which of the following statements is incorrect?

Options

A. Evaporation takes at all temperature
B. Bolling takes at specific temperature
C. Condensation Is a process which converts the water vapour Into liquid
D. Evaporation and boiling both are very fast process

Answer

To determine which statement is incorrect, let's analyze each statement one by one:

1. **Evaporation takes place at all temperatures.**
- Evaporation is the process where liquid water turns into water vapor. This process can occur at any temperature, not just high temperatures. Even at low temperatures, molecules at the surface of the liquid can gain enough energy to escape into the vapor phase. Therefore, this statement is **incorrect**.

2. **Boiling takes place at a specific temperature.**
- Boiling is a phase transition from liquid to gas that occurs at a specific temperature, known as the boiling point. For water, this is typically 100°C at standard atmospheric pressure. This statement is **correct**.

3. **Condensation is a process which converts water vapor into liquid water.**
- Condensation is indeed the process where water vapor loses energy and transforms back into liquid water. This statement is **correct**.

4. **Evaporation and boiling both are very fast processes.**
- While boiling is a rapid process that occurs at the boiling point, evaporation can occur at various rates depending on temperature and surface area. However, it is generally slower than boiling. Nevertheless, the statement does not specify the rate of evaporation relative to boiling, so it can be considered **correct** in a general sense.

Based on this analysis, the **incorrect statement** is:

**1. Evaporation takes place at all temperatures.**
