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.
