Understanding Boiling
Boiling is a fundamental physical process that involves a transition of matter from one state to another.
What is Boiling?
- Boiling refers to the transformation of a liquid into a vapor.
- This process occurs when a liquid reaches its boiling point, at which the vapor pressure of the liquid equals the surrounding pressure.
Key Characteristics of Boiling
- Transition from Liquid to Vapor: During boiling, molecules within the liquid gain enough energy to overcome intermolecular forces and escape into the gas phase.
- Temperature and Pressure Dependence: The boiling point varies with changes in pressure. For example, water boils at 100°C at 1 atmosphere of pressure but at lower temperatures at higher altitudes due to lower atmospheric pressure.
Why Option 'D' is Correct
- In the context of the question, the correct answer is option 'D', which states that boiling is a change from liquid to vapor.
- This is distinct from other phase changes such as:
- Solid to Liquid: This refers to melting, not boiling.
- Vapor to Liquid: This describes condensation, the opposite of boiling.
- Liquid to Solid: This is solidification or freezing.
Conclusion
Understanding the boiling process is essential in various fields, including chemical engineering, where controlling phase transitions can significantly impact processes and product outcomes.
