Question

A 500.0 ml. Glass filled with air is placed into water up-side-down while at 7.0°C. The water is heated to 77°C. How much air bubbles out from under the glass?

Answer 1

The answer is 125 ml air bubbles come out from under the glass

What is Charle's Law ?

Charles's Law describes the directly proportional relationship between the volume and temperature (in Kelvin) of a fixed amount of gas, when the pressure is held constant.

V∝T

or express from two volume/temperature points:

$\rm\dfrac{V_{1}}{T_{1}} =\dfrac{V_{2}}{T_{2}}$

This equation can be used to solve for initial or final value of volume or temperature

under the given condition that pressure and the number of mole of the gas stay the same.

It is given that

V₁ = 500 ml  

T₁= 7 + 273 = 280 K

T₂ = 77+273 = 350 K

​V₂= ?

Substituting the values in the above in the above equation

$\rm\dfrac{500}{280}} =\dfrac{V_{2}}{350}$

​V₂ =  625 ML

The volume of the glass is still 500 ml,

so, the volume of bubbles is 125 ml.
