The new volume of oxygen is 17.378 L.

Charles's law

“If a gas is contained in a closed chamber with constant mass and pressure, then its volume is directly proportional to its absolute temperature"

The relationship between volume and absolute temperature in the Charles equation is directly proportional. That is, if the temperature increases, the volume also increases. Conversely, if the temperature decreases, the volume of gas also decreases.

Thus, the simplest Charles law equation can be expressed as:

K = V/T

With,

V = gas volume (m³)

T = absolute temperature (K)

k : constant

So, Charles' law equation can be written as:

V₁/T₁ = V₂/T₂

Where:

V₁ = initial volume of gas = 30 L

T₁ = initial temperature of gas = 473 K

V₂ = new volume of gas = ?

T₂ = new temperature of gas = 274

On putting all these values on the above equation, we get

V₂ = (30)(274) / 473 = 17.378 L

So, the new volume of oxygen is 17.378 L.
