Question

2. Which of the following laws is applicable

for the behavior of a perfect gas

(a) Boyle’s law  

(b) Charles’law

(c) Gay-Lussac law

(d) all of the above

(e) Joule’s law

Answer 1

The correct options are:

(a) Boyle's law (states that the volume and pressure of a perfect gas are inversely proportional at constant temperature);

(b) Charles's law (states that the volume and temperature of a perfect gas are directly proportional at constant pressure);

(c) Gay-Lussac's law (states that the pressure and temperature of a perfect gas are directly proportional at constant volume).

Joule's law is in no way related to any gases. Therefore, the correct answer is (d) as long as it merges answers (a) - (c), but not (e).

Answer: (d)
