Question

What will be the new volume of a 250 mL sample of gas at 300 K and 1 atm if heated to 350 K at 1 atm?

Answer 1

`"291.67 mL"`

Explanation:

Charle’s Law: volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.

`color(white)(..)"V ∝ T"`

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

`"V"_2 = "V"_1 × "T"_2/"T"_1 = "250 mL" xx (350 cancel"K")/ (300 cancel"K") = "291.67 mL"`
