Answer:
A team of Chinese researchers have turned cheap copper into a new material “almost identical” to gold, according to a study published in peer-reviewed journal Science Advances on Saturday. The fast-moving ionized particles blasted copper atoms off the target.
hope this helps
have a good day :)
Explanation:
Answer:
Waters' boiling point decreases with increases in elevation because of the atmospheric pressure.
For example, the higher in elevation you are. The lower the atmospheric pressure is. In other words heated water reached boiling point quicker.
<span>Dissolution is the process of dissolving a solute in a solvent. I think the correct answer is B. Increasing the pressure of the solution will not affect the rate of dissolution given a solid solute since solid is non-compressible thus it is not affected that much with pressure. Also, known factors of dissolution are temperature, surface area and mixing rate.</span>
