At constant temperature, a sample of helium gas expands from 922 mL to 1.14 L against a pressure 2.33 atm Find w (in J) done by the gas (101.3 J

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

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.
