Question

The volume of a gas at 0 degree Celsius is 546cc at constant pressure. When it is heated from 30 degree Celsius to 50 degree Celsius the change in volume is

Answer 1

Explanation:

by using Charles law. it was so easy

Answer 2

Answer:

Solution

t1 =0°C, t2 =30°C

v1 =546 CC, v2 =x

α=1273

α=v2−v1v1t2−v2t1

1273=x−546546×30−x×00

1273=x−546546×30

6546×301027391=x−546

⇒60+546=x= 646 � 606

x=606

t1=30°C, t2 =50°C

v1=606, v2 =x

1273=x−606606×50−x×30

606×50+273×606=273 x+30 x

6062(50+273)=303x

100+546=x

x=646

=40CC

∴ Change in volume =646−606 =40CC
