Question

Charles' Law 5. Does the empty flask contain more air molecules at room temperature or after it was immersed in the boiling water bath? Explain your answer. 6. Why did the water rush into the flask when it was immersed in the cold water and you release the tubing? 7. a) Why was it necessary to pinch the tubing closed when transferring the flask from the boiling water bath to the cold water bath? b) Why was it necessary to pinch the tubing closed when removing out of the cold water bath after equalizing the water levels?

Explanation / Answer

Ans 5 :

According to charles law , the volume of gas is directly proportional to temperature.

It is given as : V1 T2 = V2 T1

So when the flask is immersed into boiling water , the temperature increases , which will also increase the volume of air , and since the flask has fixed volume , some of the air molecules will escape out of the flask.

So the flask contain more air molecules at room temperature rather than when immersed in boiling water bath.
