1. At high altitudes the pressurized containers may expand

because the outside air pressure is greater.

2. At high altitudes containers may explode because the

molecules inside the container are not moving as fast as those

outside.

3. At high altitudes the containers may expand because volume

is directly related to pressure.

4. At high altitudes the outside pressure may be less than inside

the container so the molecules inside have more collisions

than the particles outside over the same surface.
