Question

Which of the following does not have a fixed melting & boiling point? (a) Gold (b) Ethanol (c) Sugar solution (d) Oxygen

Answer 1

sugar solution is the answer

Answer 2

Answer:

(C) Sugar Solution

Explanation:

• Sugar solution is a mixture because using the evaporation process, sugar and water can be separated from it. A substance that is made up of two or more pure components is referred to as a mixture. These mixes are the outcome of physical transformation. Because different components are present in different quantities, mixes do not boil or melt abruptly. Thus, the melting point is variable.

• Oxygen is a sort of gas that exclusively contains oxygen atoms, ethanol is a form of alcohol, and gold is a metal. The melting and boiling points of the remaining three are consequently fixed because they all have fixed ingredients. Conversely, Sugar Solution does not.
