Exploring Connections: Kinetic Energy & Temperature

As the water in the kettle reaches its boiling point, what happens to the kinetic energy of the water molecules?

• It decreases, causing molecules to slow down.

• It remains constant, as boiling point is a fixed temperature.

• It increases, allowing more molecules to escape into the gas phase.

• It fluctuates randomly without a specific trend.

A chef notices oil heats up faster than water. What does this suggest about the particle movement in oil compared to water?

• Oil particles are stationary.

• Oil particles have the same kinetic energy as water particles.

• Oil particles have less kinetic energy than water particles.

• Oil has a lower specific heat capacity than water.
