the mass of the helium the density of the helium the volume of the helium the temperature of the helium
I gave my students this multiple choice question: A helium-filled balloon is released into the atmosphere. As the balloon rises, which would most likely increase and cause the balloon to burst?

Only one answer is correct among these 4 choices:
- the mass of the helium
- the density of the helium
- the volume of the helium
- the temperature of the helium

Could you tell me which one is correct?

the volume of the helium
