A soda bottle is flexible enough that the volume of the bottle can change even without opening it. If you have an empty soda bottle (volume 591 mL) at room temperature (20 degrees Celsius), what will the new volume be if you put it into a freezer (-4.0 degrees Celsius)?

The new volume = 542.6 ml

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature

V₁=591 ml

T₁=20+273=293 K

T₂=-4+273=269 K

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.
