lora16 [44]

Handle of frying pan would be a good use for a nonmetal. A nonmetal is neither a good thermal insulator nor a good electrical conductor. Because it is neither, it can be use as a semiconductor. It does not absorb heat that much that is why it is best in insulating.

In a solution, which pair of actions could combine to keep a concentration constant?
insens350 [35]

Answer:

B: Adding water, then adding solute

Explanation:

This is because, say you have a solution with a certain concentration.

If you add more water, it will become more diluted (less concentrated)

If you add more solute, it will become more concentrated.

Therefore if you add water and solute, it could cancel out, and the concentration would remain the same.

Hope this helps! Let me know if you have any questions/ would like anything further explained :)
