If 20.0 L of a gas is cooled from 373 K to 273K, what is the new volume?

To find the new volume of the gas when it is cooled, you can use the combined gas law, which states that the ratio of the initial volume (V1) to the initial temperature (T1) is equal to the ratio of the final volume (V2) to the final temperature (T2).

The combined gas law formula can be expressed as:

(V1 / T1) = (V2 / T2)

Given:
V1 = 20.0 L (initial volume)
T1 = 373 K (initial temperature)
T2 = 273 K (final temperature)

Let's plug in the values into the formula and solve for V2:

(20.0 L / 373 K) = (V2 / 273 K)

Now, cross multiply and solve for V2:

20.0 L * 273 K = V2 * 373 K

V2 = (20.0 L * 273 K) / 373 K

V2 ≈ 14.62 L

Therefore, when the gas is cooled from 373 K to 273 K, the new volume is approximately 14.62 L.

(V1/T1) = (V2/T2)
