Question

Prior Knowledge Question (Do this BEFORE using the Gizmo.) A small helium tank measures about two feet (60 cm) high. Yet it can fill over 50 balloons! How can such a small tank contain enough helium to fill so many balloons

Answer 1

Answer: It is because the gas tank is under a lot of pressure which causes it to occupy a lesser volume.

Explanation: This is explained using Boyle's Law.

Boyle's law states that the pressure of a given mass of gas (an ideal gas) is inversely proportional to its volume.

That is the more pressure and force exerted on a gas, the lesser the volume or space it can take up.

In this instance, the small tank can contain a lot of helium because the gas shrinks due to the amount of pressure (which is caused by the quantity of gas inputed into the tank) which creates space for more gas to occupy.

Answer 2

Check Explanation.

Step-by-step explanation:

Gas molecules are very light and can always occupy the entire volume of the container in which they reside.

They can also be easily compressed enough into small spaces too.

So, a small helium tank can contain so much helium gas to serve 50 balloons. The molecules of helium gas pumped into each balloon just expand and occupy the entirety of the balloon's volume.

These postulations are the assumptions that hold true for ideal gases.

Hope this Helps!!!
