Chemistry - Ideal Gas Question with Solution | TestHub
Match each quantity in Column I with the statements in Column II that are true (fixed amount of ideal gas of fixed molecular diameter) (a Column I entry may match more than one Column II entry):
Column I (Quantity) | Column II (Statement) |
|---|---|
(P) mean free path at constant pressure, T changes | (1) proportional to T |
(Q) mean free path at constant volume, T changes | (2) independent of T |
(R) collisions per molecule per second at constant volume, T changes | (3) proportional to |
(S) number of molecules per unit volume at constant pressure, T changes | (4) proportional to 1/T |
| (5) increases when T is raised |
Choose the option with the correct matching:
Options:
Answer:
Solution:
(P) : proportional to T, so it increases (1, 5).
(Q) does not depend on T (2).
(R) N is fixed, so collisions per molecule are proportional to , which goes as , and increase (3, 5).
(S) is proportional to 1/T and falls when T is raised (4).
Correct matching: P to 1,5; Q to 2; R to 3,5; S to 4. Answer: (C).
