Answer 1

Answer :-

Mercury is the only metal that is liquid at room temperature.

• Mercury and Gallium are the metals which are found in liquid state at room temperature.

• As they are liquids at room temperature, they are not sonorous.

• Most metals remain solid at room temperature, except mercury and gallium which remain liquid at room temperature.

• Metals produce ringing sounds when they are struck and hence, they are sonorous, except Mercury which is liquid in nature.

• Mercury is the only metal that is in liquid state at room temperature.

• Mercury is a good conductor of heat and it expands and contracts with the changes in the temperature. Hence, the slightest change in the temperature is noticed in the thermometer.

• Mercury is used in thermometer and helps to check the temperature.

• Mercury is a non-Reactive metal.
