Chemistry - Ideal Gas Question with Solution | TestHub
Match each change on an ideal gas sample (the amount is fixed except where stated) in Column I with its results in Column II (a Column I entry may match more than one Column II entry):
Column I (Change) | Column II (Result) |
|---|---|
() temperature doubled at constant volume | (1) pressure doubles |
(Q) volume doubled at constant temperature | (2) pressure halves |
() temperature doubled at constant pressure | (3) volume doubles |
(S) number of moles doubled at constant and | (4) density halves |
| (5) density doubles |
Choose the option with the correct matching:
Options:
Answer:
Solution:
() is proportional to at fixed , : pressure doubles (1). Mass and are unchanged, so density is unchanged (not listed).
(Q) = constant: pressure halves (2). Same mass in twice the volume: density halves (4).
() is proportional to at fixed : volume doubles (3). Same mass in twice the volume: density halves (4).
(S) is proportional to at fixed , : pressure doubles (1). Mass doubles in the same volume: density doubles (5).
Correct matching: to 1; Q to 2,4; to 3,4; S to 1,5. Answer: ().
