When water is actively boiling, the particles of water are gaining kinetic energy. As the temperature reaches its boiling point, the water absorbs heat, which increases the kinetic energy of the particles.
Here's a breakdown of the options you provided:
-
Particles will lose kinetic energy and increase temperature during boiling - This is incorrect. The particles gain kinetic energy and the temperature remains constant at the boiling point.
-
Particles will lose kinetic energy and decrease temperature during boiling - This is incorrect. The particles are gaining kinetic energy.
-
Particles will have the same average kinetic energy and the same temperature during boiling - This is correct. While water is boiling, its temperature remains constant at the boiling point despite the continuous addition of heat. It is during this phase change that the average kinetic energy of the particles stays the same until all the water has turned to vapor.
-
Particles have the same kinetic energy and a decrease in temperature during boiling - This is incorrect as well, as temperatures do not decrease during boiling.
Based on this analysis, the correct option would be: "Particles will have the same average kinetic energy and the same temperature during boiling."
