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

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
