3. What
Why are high-altitude weather balloo
inly partially filled when they are launched
with flying?
OER PS

Explanation:

This is because as the weather balloon rises into the atmosphere the air in the balloon will begin to fill the balloon until the balloon is overstretched. At a particular altitude, the balloon will burst.

The air in the balloon expands because the higher the altitude it does, the less the ambient atmospheric pressure is encountered. This is because the density of air decreases with altitude.  The air inside therefore gains more pressure than the ambient air pressure causing it to expands.

Filing the balloon wiht too much air at the surface may cause the balloon to burst even before it reaches the required altitude.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

can you list the answers so i can answer
