No because a room is a room, it doesn't matter what coler it would be!!!
Silver chloride is a white, crystalline solid compound that is typically represented by the chemical formula AgCl. It is not found in a specific state, but rather it is a solid at room temperature and pressure.
AgCl, or silver chloride, is a white solid at room temperature.
Mercury is a metallic chemical element that is different from gold, silver, and copper. It is a silvery-white metal that is liquid at room temperature.
Vapor comes from the water's steam so therefore, plain water is colder IF it is room temperature or colder. It obviously wouldn't be colder if it was boiling.
The same as that of the element silver, the color of which is called "silver" as a color also. A major difference is that mercury is liquid at room temperature and therefore is often more reflective than silver, which is susceptible to tarnishing.
Magnesium is a solid at room temperature. It is a metallic element with a shiny, silver-white appearance.
Silver chloride is composed of equal parts silver and chlorine. It forms a white crystalline solid at room temperature and is commonly used in photography and medical applications.
White paint will eliminate shadows making a room feel a bit larger, but much colder, go with a tan which will eliminate shadows and yet still give you that warm feel.
A room doesnt get colder before putting on a heater or something. This may feel like it because your body will feel the warm of the heat, also it will feel the cold air. This will make you feel more colder.
Silver chloride (AgCl) is a white solid at room temperature. It appears white because it absorbs all wavelengths of visible light equally, reflecting them back without any specific color being dominant.
The state of silver at room temperature is a solid.
Meaning of the question is far from clear, but the answer is probably "chill your room to -40C or colder", there is no other way. You could make an amalgam with some other metal (silver, for example) but then you don't have pure mercury anymore.
