Solution
-
"Mercury metal has a melting point of -38.83 °C." This means that, at room temperature (which is typically around 20-25 °C), mercury is in a liquid state.
-
"Bromine is a non-metal with a melting point of -7.2 °C and a boiling point of 58.8 °C." Given that room temperature is between the melting and boiling points of bromine, bromine is also a liquid at room temperature.
-
"Bromine's boiling point is 58.8 °C." This means that bromine will turn into a gas at temperatures above 58.8 °C.
So, to summarize:
- Mercury is a metal that is liquid at room temperature due to its low melting point.
- Bromine is a non-metal that is also liquid at room temperature, but will turn into a gas at temperatures above its boiling point.
