Which is the best interpretation of the two flat portions of the graph?
The correct option is: The particles will have the same average kinetic energy and the same temperature during boiling.
To determine which option describes the particles of water as the liquid water actively boils, we need to understand the process of boiling and how it affects the particles in water.
Boiling is the phase transition from a liquid state to a gas state that occurs when the temperature of a substance reaches its boiling point. During boiling, the heat energy added to the liquid water causes the water molecules to gain kinetic energy. As a result, the water molecules start moving faster and eventually break free from the liquid phase, forming water vapor or steam.
Let's examine each option:
1. The particles will lose kinetic energy and increase temperature during boiling.
This option is incorrect because during boiling, the particles of water actually gain kinetic energy rather than losing it. The increased kinetic energy allows the molecules to overcome the intermolecular forces that hold them together in the liquid phase.
2. The particles will have the same average kinetic energy and the same temperature during boiling.
This option is also incorrect. The average kinetic energy of the water molecules increases during boiling as they gain energy from external sources to transition to the gas phase. Therefore, the statement that the particles have the same average kinetic energy during boiling is inaccurate.
3. The particles will lose kinetic energy and decrease temperature during boiling.
Similarly to option 1, this option is incorrect. Boiling is characterized by the molecules gaining kinetic energy, not losing it. As the water molecules gain energy and escape the liquid phase, the temperature of the remaining liquid may not increase significantly, but it does not decrease.
4. The particles will have the same average kinetic energy and a decrease in temperature during boiling.
This option is incorrect because, as explained above, the average kinetic energy of the water molecules increases during boiling, not stays the same. Additionally, the statement regarding a decrease in temperature during boiling is inaccurate.
In conclusion, none of the given options accurately describe the particles of water as the liquid water actively boils. As the liquid water boils, the particles, or water molecules, will gain kinetic energy and increase in temperature, allowing them to transition from the liquid phase to the gas phase.
