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

Check Explanation.

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!!!

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
