Question

If the volume of a gas is doubled without changing its temperature the pressure of the gas is *

1:reduced to one-half of the original value
2:reduced to one-fourth of the original value
3:not changed​

Answer 1

Answer:

Correct option is

D

It will increase by four times its original value

The ideal gas law is the equation of state of a hypothetical ideal gas. It is a good approximation of the behaviour of many gases under many conditions

PV=nRT,

where:

P is the pressure of the gas,

V is the volume of the gas,

n is the amount of substance of gas (in moles),

R is the ideal, or universal, gas constant, equal to the product of the Boltzmann constant and the Avogadro constant,

T is the absolute temperature of the gas

P0V0=nRT0

When pressure and volume doubled,

⇒2P0×2V0⇒4P0V0=4×nRT0=nR(4T0)⇒T=4T0

Temperature is increased by 4 times.

option D is correct.
