When two gasses of different temperatures enter a room they will change the others temperature. The hotter gas will make the cooler gas warmer, and the cooler gas will make the hotter gas colder. Eventually they will start to turn towards room temperature. I hope I answered your question!
Yttrium is a solid metal at r.t.
Silver would be a solid at room temperature. This is also what happens with gold. If both were heated, then they would be liquids.
The cooler the temperature, the slower the particles move and the closer together they are because they don't need as much room. That accounts for how cooler air is thicker.
Iodine is a solid at room temperature and pressure. It sublimes, meaning it changes directly from a solid to a gas without passing through a liquid phase.
At room temperature sodium chloride is a solid.
A room that you cannot enter...
At room temperature sodium chloride is a solid.
Copper is a solid at room temperature.
Titanium is a solid at room temperature.
At room temperature the copper wire connecting your computer to the wall happens to be solid. If it were liquid, it would flow all over the place and you could not plug your computer into the wall. You do have your computer plugged in, don't you?
Vanadium is a solid metal at room temperature.
Actinium is a solid at room temperature.
