Choose the correct statement of the following:a)Conversion of solid in...
**Explanation:**
The correct statement is option 'B': "Conversion of vapours into solid without passing through the liquid state is called deposition or desublimation."
**Conversion of Vapours into Solid**
When a substance changes directly from the gaseous state to the solid state without passing through the liquid state, it is known as deposition or desublimation. This process occurs when the temperature of the gas is lowered to a point where the gas molecules lose enough energy to come together and form a solid.
**Example of Deposition**
An example of deposition is the formation of frost or dew. During the night, when the temperature drops, the water vapour in the air can undergo deposition and form ice crystals on surfaces such as grass or windows.
**Difference Between Freezing and Deposition**
It is important to note that freezing is the process of converting a liquid into a solid, whereas deposition is the process of converting vapours directly into a solid. Freezing involves a phase change from a liquid to a solid, while deposition skips the liquid phase altogether.
**Other Statements**
Let's briefly discuss the other statements for clarity:
- Option 'A': "Conversion of solid into vapours without passing through the liquid state is called vaporization." This statement is incorrect because vaporization refers to the process of converting a liquid into a gas, not a solid into a gas.
- Option 'C': "Conversion of vapours into solid without passing through the liquid state is called freezing." This statement is incorrect because freezing involves the conversion of a liquid into a solid, not vapours into a solid.
- Option 'D': "Conversion of solid into liquid is called sublimation." This statement is incorrect because sublimation refers to the process of converting a solid directly into a gas without passing through the liquid state.
Overall, option 'B' is the correct statement that describes the process of deposition or desublimation, which involves the conversion of vapours directly into a solid.
