A helium-filled weather balloon is held at ground level. The volume of the balloon is 4800 m. The pressure of the helium is 98 kPa.
Ihe balloon is released and rises to a height where the volume of the balloon is 7200 m.
(0 Calculate the new pressure of the helium. Assume that the temperature stays constant.
[21
pressure =
​

simply answer plvl=p2v2 vl =4800 p1 =98kpa

Explanation:

p2=? v2=7200m p2=plvl÷v2 thensimply you can answer it

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the answer is b i think
