Question

At room temperature, what is the only metal that is in liquid form?

Answer 1

It is the same metal that is used in thermometers. It is also the same metal used to measure atmospheric pressure. 1atm = 760 torr. Meaning at standard atmospheric pressure this metal rises 760 ml. Hopefully this will help you remember what the element is as opposed to me giving you the answer. ptable.com gives the state of the elements at the temp you set, so you can choose room temp and find the corresponding color for liquid.

Answer 2

In a easier way, or in other words it is mercury for sure
