Study Notes
Freezing Point Definition
- The freezing point is the temperature at which a liquid transforms into a solid.
- For pure substances, the freezing point is equal to the melting point.
Correct Statements about the Freezing Point
- The freezing point can vary based on pressure and the presence of impurities.
- The freezing point is a characteristic property of substances, allowing for identification.
Behavior at Freezing Point
- When a liquid reaches its freezing point, molecular motion slows down significantly.
- Energy in the form of heat is released during the freezing process, causing particles to bond and form a solid.
Examples of Freezing Points
- Water has a freezing point of 0°C (32°F) under standard atmospheric pressure.
- Different substances have distinct freezing points, such as ethanol at -114.1°C (-173.4°F).
Factors Affecting Freezing Point
- Factors that affect the freezing point include pressure, molecular structure, and the presence of solutes.
- The freezing point of a liquid is not influenced by the quantity of the liquid present.
