1. if a metal with a higher specific heat were used, would this raise or lower the final water temperature? explain

A metal with a higher specific heat would somewhat elevate the final temperature of the water. This takes place because of the transfer of the heat from one body to another. The metal, that is, the hotter body, would lose its thermal energy, and the water, that is, a cooler body would attain some of that energy. The process would take place spontaneously until and unless both the bodies attain a similar equilibrium temperature.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
