ITS URGENT PLZ HELP

calculate the volume of a gas when the temperature is decreased to 280 K if the initial volume at 350 K was 2.5 L.

Answer 1

2 L

Explanation:

At constant pressure, the volume of a gas is proportional to its temperature.

Therefore, we can write
`(V_(2) )/(V_(1) ) =(T_(2) )/(T_(1) )` ....... (1) at pressure = constant.

Given that the initial volume (
`V_(1)`) = 2.5 L and initial temperature (
`T_(1)`) = 350 K

And the final temperature (
`T_(2)`) = 280 K

Therefore, from equation (1) we get final volume (
`V_(2)`) =
`(280 * 2.5)/(350) =2` L (Answer)
