A sample of oxygen gas initially at 373 K was heated to 427 K. If the volume of the oxygen gas sample at 427 K is 735.3 mL, what was its volume at 373 K?



Expert Answer

Step 1

Given that, pressure is held constant. Volume and temperature are changing.

Step 2

Therefore, this comes under Charle’s law.

V1 / T1 = V2 /T2

Where, V1 and V2 are initial and final volume respectively. T1 and T2 are initial and final temperature respectively.

Step 3

By plugging all the values in the above equatio...
