Question

Use the graph and diagram to answer the question. Which option describes the particles of water as the liquid water actively boils? (1 point) Responses The particles will have the same average kinetic energy and the same temperature during boiling. The particles will have the same average kinetic energy and the same temperature during boiling. The particles will have the same average kinetic energy and a decrease in temperature during boiling. The particles will have the same average kinetic energy and a decrease in temperature during boiling. The particles will lose kinetic energy and decrease temperature during boiling. The particles will lose kinetic energy and decrease temperature during boiling. The particles will lose kinetic energy and increase temperature during boiling.

Answer 1

The correct response is:

"The particles will have the same average kinetic energy and the same temperature during boiling."

During boiling, the temperature of the liquid remains constant as the energy supplied goes into changing the state of the water from liquid to gas (steam), rather than increasing the kinetic energy of the particles. The average kinetic energy of the particles in the liquid state remains the same until all the water has evaporated.
