Question

At a constant pressure, an ideal gas has a volume of 200 cm³ at 25°C. If the gas is cooled to −3°C, what will be the final volume of a gas?

पर्याय

• 181 cm³

• 221 cm³

• 24 cm³

• 245 cm³

Answer 1

181 cm³

Explanation:

`"V"_1/"V"_2 = "T"_1/"T"_2`

∴ V₂ = `("V"_1"T"_2)/"T"_1 = (200  "cm"^3 xx (273 - 3) "K")/((273 + 25) "K")` = 181 cm³
