Things expand when heated, and different materials expand differently. An engineer needs to calculate HOW MUCH things expand, and factor this in when designing anything.
Platinum's state of matter at room temperature would be a solid.
Decreasing temperature would not increase the rate at which a solid dissolves
Gold as it is commonly found is a solid.
Astatine (like iodine) would be 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?
If it were a solid at room temperature, then that would be the state of matter. However, hydrogen is NOT solid at room temperature. It is a gas and that would be the state of matter.
Vanadium is a solid metal at room temperature.
Iodine is a solid when at 25 degrees centigrade (room temperature)
Presumably, phoshophorus at room temperature, would be at ... room temperature. It would be solid and melt at 44.2°C (white phosphorus: 111.56°F) or 610°C (black phosphorus: 1130°F)
Platinum's state of matter at room temperature would be a solid.
No, it would not.
Decreasing temperature would not increase the rate at which a solid dissolves
Silver would be a solid at room temperature. This is also what happens with gold. If both were heated, then they would be liquids.
Would be Solid.
Decreasing temperature would not increase the rate at which a solid dissolves
no
It is a solid, only in extreme heat it would be a liquid. And Im not sure what would make it a gas.
