Question

The volume of a gas at 20°C is 100CC at normal pressure when it is heated to 100°C its volume is 125CC at the same pressure the
volume coeficient of the gas is​

Answer 1

Answer:

The  volume coefficient of the gas 88.375 K^(-1)

Explanation:

The volume of a gas at 20°C is 100 CC at normal pressure when it is heated to 100°C its volume is 125 CC at the same pressure.

Let the volume coefficient of the gas is a

then according to the rule:

a= ΔV/VΔT

The difference in the volume is, ΔV= (125-100)= 25 CC

V= 100 CC

The change in temperature: ΔT= (100-20)= 80°C= 353.5 K

Now according to the rule:

a= 25/100 x 353.5

 = 88.375 K^(-1)

Answer 2

Answer:

0.0031 degree celsius

Explanation:

gamma= delta v / v * 1 / theta= 25/100*1/80 =

0.0031 degree celsius
