Constant Temperature during Conversion of a Liquid into a Gas
Introduction: When a liquid is heated, it eventually reaches its boiling point and starts converting into a gas. During this phase change, the temperature remains constant.
Activity:
- Materials Needed: A beaker, water, Bunsen burner, and a thermometer
- Procedure:
- Fill the beaker with water and place it on the Bunsen burner
- Heat the water gradually while stirring it continuously
- Keep measuring the temperature with the thermometer
- Observe that once the water reaches its boiling point, the temperature remains constant at 100°C until all the water has converted into steam
Explanation:
- Phase Change: When a liquid reaches its boiling point, it absorbs heat energy to break the intermolecular bonds and convert into a gas
- Constant Temperature: The absorbed heat energy is utilized in breaking the bonds rather than increasing the temperature, hence the temperature remains constant during the phase change
- Heat Absorption: The absorbed heat energy is known as the latent heat of vaporization, which is required for the phase change to occur
Conclusion:
Through this activity, it is evident that the temperature remains constant during the conversion of a liquid into a gas due to the absorption of heat energy for breaking intermolecular bonds.
