Agas is cooled from 365 k to 285 k while its volume changes from 12.8 l to 9.9 l. the initial pressure of the gas is 1.9 atm.

Assuming you want the new pressure, PV/T = PV/T , so by extension you'd have (1.9 atm)(12.8 L)/ 365 K = x atm (9.9L)/ 285 K  x= 1.918 atm

Nps pollution is caused by rainfall or snowmelt moving over and through the ground. nonpoint source pollution can include: excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. oil, grease and toxic chemicals from urban runoff and energy production
