If no of moles and absolute temperature is double then Pressure will be
A: 1/2 times
B: remain Same
C: 8 times
D: 4 times​

Verified Answer :

When the number of moles and absolute temperature both double, the pressure of the gas will be 4 times its original value. This result follows from the Ideal Gas Law. Hence, the correct answer is D: 4 times.

Effect of Doubling Moles and Temperature on Pressure

To determine how the pressure changes when the number of moles and the absolute temperature are both doubled, we can use the Ideal Gas Law equation: PV = nRT.

Here,

P is pressure

V is volume

n is the number of moles

R is the gas constant

T is absolute temperature

Initially, we have :P1V = n1RT1

After doubling the number of moles and the absolute temperature, the equation becomes:

P2V = (2n1)R(2T1)

Simplifying this, we get :P2V = 4n1RT1

To compare with the initial equation P1V = n1RT1, we see that P2 is 4 times P1. Therefore, the pressure will be 4 times its original value.

Thus, the correct answer is :D: 4 times
