The pressure of 4.2L of nitrogen gas in a flexible container is decreased to one-half its original pressure and its absolute temperature is increased to double the original temperature what is tge volume now

V₂ = 16.8V₁

Explanation:

P₁ = 4.2L   =>   P₂ = 1/2P₁ => Decreasing Pressure => Increases Volume

V₁ = V₁      =>    V₂ = ?

T₁ = T₁       =>    T₂ = 2T₁  => Increasing Temperature => Increases Volume

P₁V₁/T₁ = P₂V₂/T₂ => V₂ = P₁V₁T₂ / P₂T₁ = (4.2P₁)(V₁)(2T₁) / (P₁/2)(T₁) = 16.8V₁

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.
