Question

6.0 L of oxygen gas is at a temperature of 5K. If the temperature of the gas is lowered to 1K at constant pressure, what is the new volume of the gas?

Answer 1

Answer:1.2 L

Explanation: according to Charles law, the volume of a fixed mass of gas is directly proportional to it's temperature.

Volume is the size of the space that a gas occupies and it can be measured in liters, cubic meters, cubic decimeters etc.

Answer 2

THE NEW VOLUME AT 1 K IS 1.2 L

Step-by-step explanation:

Using Charles' law which states that the volume of a given gas is directly proportional to its temperature provided the pressure remains constant.

Mathematically written as;

V1/T1 = V2/T2 at constant pressure

V1 = Initial volume = 6L

T1 = initial temperature = 5K

T2 = Final temperature = 1K

V2 = final volume = unknown

Re-arranging the equation by making V2 the subject of the equation, we obtain;

V2 = V1 T2 / T1

V2 = 6 * 1 / 5

V2 = 1.2 L

The new volume of the gas sample at 1 K is 1,2 L
