Question

a gas occupies 3litres at o degree Celsius . What volume will it occupy at -20degree celcius , pressure remaining constant

Answer 1

V is directly proportional to T
0 degree celsius = 273k=T1
-20 degree celsius=253k=T2
 V1/V2=T1/T2
3//V2=273/253
V2=2.78 litres

Answer 2

Answer:

2.78 litres

Explanation:

V is directly proportional to T

0 degree celsius = 273k=T1

-20 degree celsius=253k=T2

V1/V2=T1/T2

3//V2=273/253

V2=2.78 litres
