Question

You are in charge of inflating parade balloons. You just learned that the temperature will rise 15°C between early morning and the time the parade starts. How will this information affect the way you inflate the balloons?

Answer 1

This information means the balloons should be under inflated because as the temperature increases the volume will increase.

Explanation:

Charles Law states that Volume and Temperature are directly related .This means as the temperature increases the volume will increase.
If the balloons were fully inflated when the temperature increased the the balloons might exploded.

Charles Law `V_1/ T_1 = V_2/T_2`

`15^o` C increase would be a ratio increase of `15/273`
because `1^o C` = `1^oK`

`0^oC` = `273^oK`

so an increase of `15^oC` is the same as increase of `15^oK`

`15/273` = 5.5% increase.

So the balloons must be under inflated at least 5.5% to avoid the gallons exploding because of the increase in volume.
