At a temperature of , which of the following elements would be in the liquid phase at approximately ?
A
Bromine (Br)
B
Oxygen (O)
C
Iron (Fe)
D
Mercury (Hg)
Verified step by step guidance1
Identify the boiling points of each element at 1 atm pressure. The boiling point is the temperature at which a substance changes from liquid to gas.
Compare the given temperature (1000 K) to the boiling points of Bromine (Br), Oxygen (O), Iron (Fe), and Mercury (Hg).
Determine the phase of each element at 1000 K by checking if the temperature is below or above their boiling points:
- If the temperature is below the boiling point, the element is in the liquid phase.
- If the temperature is above the boiling point, the element is in the gas phase.
