Question

what is the only metal that is liquid at room temperature on earth? enter the answer

Explanation:

This question is about identifying the metal that exists in liquid form at room temperature. In the field of Chemistry (a subfield of Natural Science), it is a well - known fact that Mercury (Hg) has a relatively low melting point ( - 38.83 °C) and a boiling point of 356.73 °C. Room temperature is typically around 20 - 25 °C, which is well above Mercury's melting point and below its boiling point, so Mercury is liquid at room temperature.

Answer:

Mercury (or Hg)
