Detailed explanation-1: -Expert-Verified Answer. The matter can undergo a change in the state of matter. The liquid mercury matter can be converted into solid by removing energy to decrease motion. Thus, option D is correct.
Detailed explanation-2: -Mercury can be solidified when its temperature is brought to its freezing point. However, when returned to room temperature conditions, mercury does not exist in solid state for long, and returns back to its more common liquid form.
Detailed explanation-3: -According to modern chemistry, you cannot solidify mercury at room temperature; you can solidify mercury only if you take it to-38 degrees Centigrade.
Detailed explanation-4: -Why Mercury Is a Liquid. Mercury has a low melting point and is a liquid at ordinary temperatures because its electrons aren’t readily shared between its atoms. This is a consequence of mercury atoms containing so many protons and electrons and the way its electrons organize around the nucleus.
Detailed explanation-5: -Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature.
