Answer to Question #97181 in General Chemistry for Mara Bello

Question

How will the volume of 0.50 mol of a gas behave if the temperature is raised from 30oC to 60oC at constant pressure

Answer 1

Pressure is constant.

Let the initial volume be V at temperature 30°C.

Let the final volume be V1 at temperature 60°C.

Initial temperature is T=303K

Final temperature is T1 = 333K

According to Charles Law ;

$V/T = constant$

$V/T=V1/T1$

$V1=V×T1/T$

$V1=V×333/303$

$V1=1.099V$ (Answer)

The new volume becomes 1.099 times original volume.
