Answer

The volume will be 50 L

Explanation

From Kelvin Law of Temperature, we know that

[tex]V_{1} T_{1} =V_{2} T_{2}[/tex]

We know that

[tex]V_{1}[/tex] = 200 L

[tex]T_1[/tex] = 100 K

[tex]T_2[/tex]= 400 K

So,

[tex]V_{2} = V_{1} T_{1}/T_{2}[/tex]

[tex]V_{2} = 200*100/400[/tex]

[tex]V_{2} = 50 L[/tex]

The answer of the givern question is 50L


znk

The new volume is 800 L.

From Charles’ Law, we know that

V₁/T₁ = V₂/T₂

Then

V₂ = V₁ × T₂/T₁

V₁ = 200 L; T₁ = 100 K

V₂ = ?;        T₂ = 400 K

∴ V₂ = 200 L × (400 K/100 K) = 800 L
