A spherical balloon is filled with helium inside a factory where the temperature is 75
degrees Fahrenheit F to a pressure of 15 pounds-force per square inch psi.
The filled balloon now has a diameter of 24 inches in.
Helium is an ideal gas with a molecular weight of 4 grams per mole
mol
6.
Assume the amount of gas and the pressure inside the balloon remain constant.
The balloon is taken outside to be used as a decoration at a fall garden party, where
the temperature is 55 degrees Fahrenheit [ F].
Determine the volume of the filled balloon in the cooler conditions, in units of cubic
inches [in ].

Expert Solution

Step 1

Given:

The initial temperature is T=75 ^oF.

The final temperature is T'=55 ^oF.

The diameter of the balloon is d=24 in.

The pressure is P=35 psi.

According to gas equation, the expression for volume (V') of the filled balloon is:

$\begin{array}{rcl} \frac{P V}{T} & = & \frac{P V'}{T'} \\ \frac{V}{T} & = & \frac{V'}{T'} \\ \frac{\frac{4}{3} π {(\frac{d}{2})}^{3}}{T} & = & \frac{V'}{T'} \\ V' & = & \frac{π d^{3} T'}{6 T} \end{array}$
