Question

The volume of a mixed amount of gas doubled, and the absolute temperature is doubled. According to the ideal gas law, how has the pressure of the gas changed

Answer 1

D

Step-by-step explanation:

It has stayed the same.

Answer 2

Answer : The pressure of the gas would be unchanged.

Explanation : Given,

Ideal gas law :
`PV=nRT`

where,

P = pressure of gas

V = volume of gas

T = temperature of gas

n = moles of gas

R = Gas constant

The expression for pressure is,

`P=(nRT)/(V)`

when the volume and temperature of gas doubled then the expression for pressure is,

`P_1=(nR* 2T)/(2V)=(nRT)/(V)=P`

From this we conclude that the
`P=P_1` that means pressure of the gas would be unchanged.
