As a subject matter expert in the field of physical science, I can provide an in-depth explanation to the question of whether water can get hotter than its boiling point.
Water, being a substance with a well-defined phase transition, has a boiling point of 100 degrees Celsius (212 degrees Fahrenheit) under standard atmospheric pressure. This is the temperature at which the kinetic energy of the water molecules is sufficient to overcome the intermolecular forces that hold them together in the liquid phase, allowing them to escape as a gas. However, the boiling point of water is not a fixed value; it is dependent on the pressure exerted on the water. At higher pressures, the boiling point increases, and at lower pressures, it decreases.
The concept of water getting hotter than its boiling point is intriguing and relates to a phenomenon known as superheating. Superheating is the process by which a liquid is heated beyond its boiling point without boiling. This can occur if the liquid is free from nucleation sites, which are the tiny disturbances or impurities that provide a starting point for the formation of bubbles as the liquid turns into a gas. In a perfectly pure, still, and undisturbed body of water, it is theoretically possible to superheat the water to temperatures above 100 degrees Celsius. However, in practice, this is rare because most water contains impurities that act as nucleation sites, causing it to boil at or near its normal boiling point.
When water is in the gaseous state, it is referred to as steam or water vapor. The temperature of steam can indeed be much higher than the boiling point of water. As the reference material suggests, in the gas form, water molecules are spread out and have a lot of room to move, which allows them to reach higher temperatures. The temperature of steam can be increased by adding more heat energy. This is why steam can be used for various industrial processes that require high temperatures, such as in power plants where steam is used to drive turbines.
It is also important to note that water can exist in a supercooled state, where it remains in the liquid phase even below its freezing point of 0 degrees Celsius (32 degrees Fahrenheit). This happens when the water is cooled very slowly and does not have the impurities or disturbances necessary to initiate the crystallization process that forms ice. However, supercooled water is in a metastable state and can quickly freeze if disturbed.
In summary, while water cannot be heated above its boiling point in the liquid phase under normal conditions, it can exist in a superheated state or as superheated steam at temperatures higher than its boiling point. The behavior of water with respect to temperature and phase changes is complex and depends on various factors, including pressure, impurities, and the rate of heating or cooling.

After water changes from a liquid to a gas (at 212 degrees Fahrenheit) it can actually heat up much hotter than that. In the gas form, water molecules are spread out and have a lot of room to move and get much hotter than the other two phases (liquid and ice). And water freezes at 32 degrees Fahrenheit.
