Question

The above shows a gas system which has a volume of 250 mL

at 280K. If the pressure keep constant,
what is the volume of the gas system at 250 K?

Answer 1

A gas system which has a volume of 250 ml at 280K. If the pressure keep constant, 223.15 ml is the volume of the gas system at 250 K.

Step-by-step explanation:

Data given:

A gas system given with conditions as:

initial volume of gas, V1= 250 ml

initial temperature of the gas, T1= 280 K

Pressure = constant

Final volume of the gas V2= ?

Final temperature of the gas, T2 = 250 K

From the Charles' Law

`(V1)/(T1)` =
`(V2)/(T2)`

rearranging the equation, we get

V2 =
`(V1T2)/(T1)`

Putting the values in the equation, we get

V2 =
`(250 X 250)/(280)`

V2 = 223.21 ml

When the gas system has its temperature reduced to 250 K the volume is reduced to 223.21 ml.
