Question

a sample of helium gas is heated from 20c to 40c.This heating process causes the gas to expand to a volume of 585ml.what was the orignal volume of the helium gas​

Answer 2

Answer:

547.6 ml

Explanation:

Charles Law states that volume of a gas is directly proportional to its temperature if the pressure remains constant.

V∝T

$\frac{V1} {V2} =\frac{T1}{T2}$

Let the original volume be V1, and given V2(after heating)=585ml = 0.585 litre,

We know that Temperature in kelvin = Temp in celsius + 273

T1= 20C = 293K

T2= 40C = 313K

Now putting T1,T2,V2 in equation:

$\frac{V1}{0.585}=\frac{293}{313}$

Solving this, we get V1=0.5476L

Hence, V1, the original volume = 547.6 ml
