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.

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  mole will also be same .

For cylinder A

Temperature T , volume 3V , pressure  P₁ , no of mole = n

so

P₁ X 3V = n R T

For cylinder B

Temperature T , volume V , pressure  P₂ ,no of  mole = n

so

P₂ X V = n R T

From the two equation above

P₁ X 3V = P₂ X V

P₁ = P₂ / 3

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

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
