To solve this problem, we can use the combined gas law formula:

(P1 * V1) / T1 = (P2 * V2) / T2

Where:

P1 = initial pressure

V1 = initial volume

T1 = initial temperature

P2 = final pressure

V2 = final volume

T2 = final temperature

Given:

P1 = P2 (same pressure)

V1 = 200 cm3

T1 = 270 K

T2 = 127 K

Plugging in the values:

(200 * 270) / 270 = (V2 * 127) / 127

200 = V2

Therefore, the volume of oxygen gas at 127oC at the same pressure will be 200 cm3.

(P1 * V1) / T1 = (P2 * V2) / T2

Where:

P1 = initial pressure

V1 = initial volume

T1 = initial temperature

P2 = final pressure

V2 = final volume

T2 = final temperature

Given:

P1 = P2 (same pressure)

V1 = 200 cm3

T1 = 270 K

T2 = 127 K

Plugging in the values:

(200 * 270) / 270 = (V2 * 127) / 127

200 = V2

Therefore, the volume of oxygen gas at 127oC at the same pressure will be 200 cm3.
