Aballoon is filled with 5 grams of helium gas. if the balloon takes up 10 ml of space and has a pressure of 20 mm hg, which gas law needs to be used to find the temperature inside the balloon

We will use ideal gas law to find the temperature inside the balloon.

The temperature inside the balloon is 0.002564 K.

Explanation:

We will use ideal gas law , given as :

PV = nRT

where,

P = Pressure of gas

V = Volume of gas

n = number of moles of gas

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of gas

So,using ideal gas equation to find the temperature inside the balloon:

PV = nRT

where,

P =  20 mmHg =

V = 10 mL  = 0.010 L

n = =

R =  0.0821 L.atm/mol.K

T = Temperature of helium gas = ?

Putting values in above equation, we get:

The temperature inside the balloon is 0.002564 K.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
