+1632 You could observe it, if it is solid, it would have a solid form and you could feel it and it would be hard, if its liquid it would be oozy or drip around, and you could put your hand through it, if it is a gas you can see it, or smell it. To know what a specific element is at, at room temperature, you can either search it up, or do an experiment. And sometimes it just is hard to tell.
