Correct option is C)

P∝T⇒T 1 P 1 = T 2 P 2 ⇒ T 2 = 2T P ⇒P 2 =4atm

Percentage increase=

2 (4−2) ×100=100%

A 50% B 100% C 150% D 200% Open in App Solution

The correct option is **B** 100%

Given information:

Initial pressure of the gas

P 1 = 1 a t m

Initial temperature of the gas

T 1 = T K

Final temperature of the gas

T 2 = 2 T K

Final Pressure of the gas

P 2 = ?

From Gay Lussac's law,

P 1 T 1 = P 2 T 2 at constant volume. 1 T = P 2 2 T Hence, P 2 = 2 a t m

Increase in pressure

= 2 − 1 = 1 atm

Percentage increase in pressure

=

increase in pressure

initial pressure × 100 = 1 1 × 100 = 100 %

The pressure is inversely proportional to the volume (Boyle’s Law) and directly proportional to the temperature (Gay Lussac’s Law)

So it will double and divide by four. The result is that it halves.

For a ideal gas pressure, temperature and volume is related by below relationship.

P = R*T/V

Here, R is gas constant.

So if we do Consider revised state pressure by P1 then,

P1 = R*2T/4V P1/P = 1/2 P1 = P/2

So pressure will be 1/2 of the original state..

What is the pressure of a gas if the temperature of the gas is doubled and the volume is quadrupled?

For an ideal gas, PV=nRT, PV=nRT, where P,V,n,R P,V,n,R and T T

are the pressure, volume, number of moles of gas present, gas constant and temperature respectively.

Hence, if the number of moles of the gas is constant,

PV T PVT is constant. ⇒ P 1 V 1 T 1 = P 2 V 2 T 2 ⇒P1V1T1=P2V2T2 for constant n. n. ⇒ P 2 P 1 = V 1 T 2 V 2 T 1 = V 1 V 2 × T 2 T 1 .

⇒P2P1=V1T2V2T1=V1V2×T2T1.

It is given that T 2 =2 T 1 T2=2T1 and V 2 =4 V 1 . V2=4V1.

\Rightarrow\qquad \frac{P_2}{P_1}=\frac{V_1}{4V_1}\times \frac{2T_1}{T_

\Rightarrow\qquad \frac{P_2}{P_1}=\frac{V_1}{4V_1}\times \frac{2T_1}{T_

The relationship is as following:

P1 * V1 / T1 =P2 * V2 / T2

P2 = P1 * V1 / V2 / T1 * T2

P2 = P1 * V1 / (4 V1) / T1 * (T1 * 2)

P2 = P1 (2 / 4) P2 = 1/2 * P1

The new pressure (P2) is half the initial pressure (P1)
