HELP MY TEST IS TIMED: A sample of methane gas is 22.8 L at 313 Kelvin and 4.00 atm. What will its pressure be at 341 K and constant volume?

3.7 atm


4.4 atm


2.4 atm


.15 atm

Respuesta :

Answer:

option B.

Explanation:

Given,

Volume,V₁ = 22.8 L

T₁ = 313 K

P₁ = 4 atm

T₂ = 341 K

P₂ = ?

Volume is constant.

Using ideal gas law

[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]

[tex]\dfrac{4}{313}=\dfrac{P_2}{341}[/tex]

[tex]P_2 = \dfrac{4}{313}\times 341[/tex]

[tex]P_ 2 = 4.36\ atm[/tex]

Pressure of the tank is equal to 4.36 atm.

Hence, the correct answer is option B.
