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:
The graph will begin at 20 °C and have temperature on the y-axis and time on the x-axis. The line will be a downwards sloping one, until the value of temperature of the graph reaches 0 °C. There, it will become horizontal for a small amount of time, and then continue to slope downwards until the graph reaches -20 <span>°C.
The horizontal region is where the freezing of water will take place, and there is no temperature change that occurs when a state change is taking place. This is because the energy involved then is latent energy.</span>
Liquid into solid, gas into a liquid, gas into a solid (deposition).
Kinetic energy is all about motion. If you think about it, the particles are going from a more chaotic state to a more orderly arrangement which reduces the kinetic energy.
