A clear colorless liquid in an open beaker was heated to boiling. The liquid began to boil at 110°C, and as vapors escaped, the temperature of boiling gradually increased to 115°C, at which the heating was stopped. On the basis of this information, we can say that the material in the beaker was a?
mixture?
heterogeneous solution
Based on the given information, we can conclude that the material in the beaker was a pure substance. The fact that the liquid began to boil at a specific temperature and continued to heat up until reaching 115°C suggests that there was a consistent composition and pressure of the substance throughout the heating process.
To determine the material in the beaker, we need to analyze the boiling point and behavior of the substance during heating.
In this scenario, the clear colorless liquid started boiling at 110°C and continued to boil until it reached 115°C, at which point the heating was stopped.
The boiling point of a substance is generally a characteristic property that is specific to the substance. Different substances have different boiling points, and this information can help identify the material.
Based on the given information, we can infer that the substance in the beaker was a pure compound with a boiling point between 110°C and 115°C. Since the liquid was clear and colorless, it rules out certain substances like colored compounds or mixtures with impurities that would affect the color.
To further narrow down the possibilities, it would be helpful to consult a list of boiling points for known substances or consult relevant databases. By comparing the boiling points of different substances, you can determine which substance matches the temperature range provided (in this case, between 110°C and 115°C).
