Select all that apply

When a balloon rises high enough in the atmosphere ,why might it burst ??

• Lightening strikes it

• the pressure on the outside is much less than the pressure inside and it expands until it bursts

• it freezes

• it gets too hot

Why does a balloon near Earth's surface stop expanding after you stop blowing into it and it tied up ??

• its too thick to expand .

• The pressure on the inside is greater than the pressure in the outside

• Mr. Zimer wills it to be so

• The pressure from the air around it is the same or greater than the pressure on the outside
