please solve if the pressure of 200cm cube of a gas is half at constant temperature. what will be the new volume​

400 cm³

Explanation:

Let p₁ Pa be the original pressure of the gas

p₂ Pa be the new pressure of the gas

V₁ m³ be the original volume of the gas

V₂ m³ be the new volume of the gas

According to Boyle's Law,

p₁V₁ = p₂V₂

p₁ × 0.0002 = 1/2 p₁ × V₂

0.0002 = 1/2 × V₂

V₂ = 0.0004

∴ The new volume of the gas = 0.0004 m³ = 400 cm³

beta decay is the answer
