* Boiling Point: Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure. This means that the particles in boiling water have enough energy to overcome the forces holding them together as a liquid, and they transition into a gaseous state (steam).

* Temperature and Kinetic Energy: Temperature is a measure of the average kinetic energy of the particles in a substance. The higher the temperature, the faster the particles are moving.

* Steam vs. Water: While a stream at 110 degrees Celsius is hotter than boiling water, it's still in a liquid state. The particles in the stream are moving faster than in water at room temperature, but they are not moving as fast as the particles in boiling water, which are transitioning to a gas.

In summary: Even though the stream is at a higher temperature, the particles in boiling water have the most kinetic energy because they are transitioning from a liquid to a gas.
