To enable the gases inside the balloon to expand which they do when the balloon reaches high altitudes. At this point the balloon becomes much larger.
Malleable
provided the balloon has not reached its elastic limit (it has burst!), the air pressure inside and outside will essentially be equal. [The pressure inside will be slightly less, which is where the lift comes from.] But even at altitude, the pressure will be approximately equal in and out, for at altitude, the balloon will have swelled, thus reducing the internal pressure. It will eventually reach an altitude at which the internal pressure and the external pressure will be equal, and the balloon will have reached maximum expansion. Filled at sea level, a balloon will seem empty and floppy, and very tall and thin. At altitude the balloon will fill out as the external pressure reduces.
The ozone layer is very thin.
Helium is not ductile. Helium is a gas, and ductile refers to metals, and basically is the ability to be drawn or pulled into a thin wire. Clearly, helium cannot be pulled into a thin wire.
A substance is considered to be ductile, if it can be hammered out thin or drawn into a wire.
The metallic property of ductility allows it to be drawn into thin wires.
If perfume is sprayed inside a balloon and then the balloon is blown up, you can still smell the perfume from the outside of the balloon. This is because the material of the balloon is thin.
No, the weather is weather. The ATMOSPHERE is the thin layer of gases.
Ductile.
DUCTILITY
Ectomorph is a tall and thin body type.
It depends on the weather
The ability to be drawn into a thin wire is a property known as ductility. Iron has ductility.
chemical property
copper can be drawn into thin, long wires~`
I am tall and thin is 'je suis grand et mince' in French.
Property of a material by virtue of which, it can be drawn into thin.. wire.
