A gas is contained in a tick walled balloon. When the pressure changes from 2. 95atm to ___atm, the volume changes from 7. 456L

tia_tia [17]

A gas is contained in a tick-walled balloon. When the pressure changes from 2. 95atm to <u>2.57</u> atm. p.

<h3>What is pressure?</h3>

Pressure is a force perpendicular to the unit area on which it is applied.

Given that, P1, the initial pressure is 2.95 atm

The initial volume, V1 = 7.456 L

The final volume, V2 = 4.782 L

The initial temperature, T1 = 379k

The final temperature, T2 = 212k

The equation will be

$\dfrac{P_1V_1}{T_1 } =\dfrac{P_2V_2}{T_2}$

Putting the values in the equation

$\dfrac{2.95 \times 7.456 L }{379k } =\dfrac{P_2\times 4.782 L}{212k}\\\\\\P_2 = \dfrac{2.95 \times 7.456 L \times 212k }{379k \times 4.782 L} = 2.57\;atm.$

Thus, the pressure changes from 2. 95atm to <u>2.57</u> atm p.
