The temperature of a gas is increased by $1°\mathrm{C}$. Then from the following statements pick out the correct one.

a) The volume increases by $1/273$ of its volume at $0°\mathrm{C}$ at constant pressure

b) The pressure increases by $1/273$ of its pressure at $0°\mathrm{C}$ at constant volume

c) The volume decreases by $1/273$ of its volume at $0°\mathrm{C}$

d) The pressure is doubled at $0°\mathrm{C}$

Given data:

To find the correct statements from the given options.

Formula/Concept to be used:

State of matter

Detailed Solution:

Statement 1 states Charle’s law, 

V=${\mathrm{V}}_0+{\mathrm{V}}_0/273$

Where, 

V= Volume at 1${}^{\circ }\mathrm{C}$

V₀= Volume at 0${}^{\circ }\mathrm{C}$

Statement 2 states Gay Lussac’s law

P=P${}_0+{\mathrm{V}}_0/273$

Where,

P= Pressure at 1${}^{\circ }\mathrm{C}$

P₀= Pressure at 0${}^{\circ }\mathrm{C}$

Therefore, Option C is the correct answer.
