Agas-filled weather balloon has a volume of 59.0 l at ground level, where the pressure is 759 mmhg and the temperature is 20.4 "c. after being released, the balloon rises to an altitude where the temperature is -3.81 â°c and the pressure is 0.0819 atm. what is the weather balloon's volume at the higher altitude? v = 43344.9 l

Answer : The volume of balloon at higher altitude will be 654.338 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

where,

= initial pressure of gas =

conversion used : (1 atm = 760 mmHg)

= final pressure of gas = 0.0819 atm

= initial volume of gas = 59.0 L

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above equation, we get:

The final volume will be, 654.338 L

Therefore, the volume of balloon at higher altitude will be 654.338 L

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
