Answer #1

This is a simple example of Charles' law

V₁/T₁=V₂/T₂. V₁ and T₁ are initial values and V₂ and T₂ are final values.

which states that the volume of a gas is directly proportional to its temperature in K.

Here V₁=50ml. ,T₁=15℃=15+273.15=288.15K

T₂=35℃=35+273.15= 308.15K .We have to find V₂

From the equation V₂=(V₁×T₂)/T₁

=(50×308.15)/288.15 = 53.47ml

New volume of gas = 53.47ml
