Question

In a process the density of a gas remains constant If the temperature is doubled, then the change in the pressure will be
(A) 100% increase
(B) 200% increase
(C) 50% decrease
(D) 25% decrease
A
B​

Answer 1

Answer:

A

Explanation:

since the density is constant, pressure of the gas is directly proportional to temperature.

as the temperature got doubled, pressure also gets doubled which means there is a 100% increase in the pressure.

Answer 2

Answer:

The pressure will be 100% increased (option a).

Explanation:

We have,

PV=nRT and V= m/ρ.

So, p m/ρ=nRT.

If ρ is constant, then

   P∝T

 If the temperature is double then pressure is also doubled. Hence there is a 100 % increase in pressure.
