Two cylinders A and B at the same temperature contain the same quantity of the same kind of gas. Cylinder A has three times the volume of cylinder B. What can you conclude about the pressures the gases exert? Show all workings. [15 marks] a. b. c. d. The density of gas in A and B are the same. The pressure in A is three times the pressure in B. The pressures in A and B must be equal. The pressure in A must be one-third the pressure in B.

Respuesta :

Answer:

so pressure in A must be one third the pressure in B

Explanation:

We shall apply gas law to the cylinders A and B . Since their quantity are same so their no of Ā mole will also be same .

For cylinder A

Temperature T , volume 3V , pressure Ā Pā‚ , no of mole = n

so

Pā‚ X 3V = n R T

For cylinder B

Temperature T , volume V , pressure Ā Pā‚‚ ,no of Ā mole = n

so

Pā‚‚ X V = n R T

From the two equation above

Pā‚ X 3V = Pā‚‚ X V

[tex]\frac{P_1}{P_2}=\frac{1}{3}[/tex]

Pā‚ = Pā‚‚ / 3

so pressure in A must be one third the pressure in B
