Question

The temperature of a 3.0L sample of gas is lowered from 350K to 275K. What will be the resulting volume of the gas?

Law being used: ___________ FORMULA WORK ANSWER

Given 1:__________

Given 2:__________

Given 3:__________

Answer 1

Solution:

Pressure is constant.

Law being used: Charles' law

Given 1: __ V₁ = 3.0 L __

Given 2: __ T₁ = 350 K __

Given 3: __T₂ = 275 K __

FORMULA:

V₁ / T₁ = V₂ / T₂

WORK:

V₁*T₂ = V₂*T₁

(3.0 L) * (275 K) = (V₂) * (350 K)

V2 = (3.0 * 275) / 350 = 2.357 L

V₂ = 2.357 L = 2.4 L

ANSWER: V₂ = 2.4 L
