Students slowly heat liquid water from a low temperature to a much higher one. They measure the temperature of the water as soon as it starts to produce steam. What are the students trying to determine from this experiment?

The question describes an experiment where students heat liquid water while monitoring the temperature. They heat the water until the water starts to produce steam, also called water vapor. They measure the temperature when this begins to occur.

The process of turning matter from a liquid state to a gas state is known as boiling. In order to boil a substance, we need to add heat. The amount of heat needed depends on the substance, as different substances boil at different temperatures.

The temperature at which matter begins to boil or change from a liquid state to a gas state is called the boiling point. The boiling point of a substance can be determined by heating the substance until vapors begin to be produced. The temperature at which this process begins is the boiling point.

So, by performing the experiment, the students are trying to determine the boiling point of water.
