Question

I need the variables in the chart to be answered.

Answer 1

Answer:

Explanation:

Given data:

Initial temperature = 295 K

Initial volume = 1.0 L

Values of A,B, C and D.

Solution:

As it is mentioned in question V₁ and T₁ are the first readings of table thus,

V₁/T₁  =  V₂/T₂

V₁ = Initial volume

T₁  = Initial temperature

V₂ = Final volume

T₂ = Final temperature

For A:

V₁/T₁  =  V₂/T₂

1.0 L / 295 K = 1.3 L /T₂

T₂ = 1.3 L × 295 K / 1.0 L

T₂ = 383.5 K

For B:

V₁/T₁  =  V₂/T₂

1.0 L / 295 K = V₂ /250 k

V₂ =  1.0 L × 250 k/ 295 K

V₂ = 250 k.L/ 295 K

V₂ = 0.85 L

For C:

V₁/T₁  =  V₂/T₂

1.0 L / 295 K = V₂ /325 k

V₂ =  1.0 L × 325 k/ 295 K

V₂ = 325 k.L/ 295 K

V₂ = 1.1 L

For D:

V₁/T₁  =  V₂/T₂

1.0 L / 295 K = 0.75 L /T₂

T₂ = 0.75 L × 295 K / 1.0 L

T₂ = 221.25 K
