Smell Unit Test

Chris has two tanks of helium gas. She wants to find out which tank has the most gas in it, so she can blow up balloons for a party. Chris thinks that measuring the masses of the two tanks will help her identify which one contains the most gas. 

Will comparing the mass of the tanks help Chris know which one has the most gas in it?

• Yes

• No
