Question

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

Answer 1

option B.

Step-by-step explanation:

Given,

Volume,V₁ = 22.8 L

T₁ = 313 K

P₁ = 4 atm

T₂ = 341 K

P₂ = ?

Volume is constant.

Using ideal gas law

`(P_1)/(T_1)=(P_2)/(T_2)`

`(4)/(313)=(P_2)/(341)`

`P_2 = (4)/(313)* 341`

`P_ 2 = 4.36\ atm`

Pressure of the tank is equal to 4.36 atm.

Hence, the correct answer is option B.
