This is because different substances have varying inter molecular forces due to electron distributions. Also the weakest of the attractive forces are found in the gases and the stronger ones are found in the solids.
Bromine is a liquid at room temperature
It is supposed that lawrencium is a solid metal at room temperature.
There are several substances that are a gas at room temperature. These include argon, oxygen, hydrogen, helium, and neon.
iodine
ice can melt at room temperature. Anything that is liquid at room temperature would, in its frozen state, melt at room temperature. Oils, beverages and mercury - if in a frozen state - would melt when exposed to room temperature.
all substances can be in any state but at different temperatures but at room temperature yes it is a solid
Bromine is a liquid at room temperature
elements can combine to form new substances with different properties.

There are several substances that are a gas at room temperature. These include argon, oxygen, hydrogen, helium, and neon.
Some examples of substances that are solids at room temperature include grease. This becomes like a gelatin at room temperature. Butter is also an example.
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
ALL liquid substances at room temperature become gaseous at higher (sometimes much higher) temperature called boiling point, unless they decompose at lower temperature.
