Question

Which option describes the particles of water as the liquid water actively boils?

the particles will lose kinetic energy and decrease temperature during boiling
the particles will lose kinetic energy and increase 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

Answer 1

what does temperature measure?

the average kinetic energy of the particles
the heat of the particles
the total energy of the particles
the empty space between the particles

Answer 2

The correct option that describes the particles of water as liquid water actively boils is:

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

During boiling, all the particles of water that are at the boiling point have a constant temperature, and although individual particles may have varying kinetic energies, the average kinetic energy remains the same across the liquid. This is because the heat energy that is added at boiling point goes into transforming the liquid into vapor, rather than increasing the temperature of the liquid.

Answer 3

Temperature measures **the average kinetic energy of the particles** in a substance. It reflects how fast the particles are moving; higher temperatures indicate higher average kinetic energy, while lower temperatures indicate lower average kinetic energy.
