At a 25 c and 760 mm of Hg pressure a gas ocupies 300 ml volume.What will be its presstre at a height where temperature is 10°c andvolume of the gas is 640 ml

Answer»

P1=760 mm Hg

V1=300 mL

T1=298k

V2=640mL

T2=283k

P2= ?

Now,

We know that;

P1 V1 = P2 V2 is same as P1 V1/T1 = P2 V2/T2

=760×300/298=640×P2/283

= 338.317953020134
