P1V1= P2V2
V1 = V2 ÷ T1T2
P1T1 = P2T2
P1V1 ÷ T1 = P1V1 ÷ T2
Correct answer is A
Boyle‘s law stats that the volume of a given mass of a gas, at a constant temperature is inversely proportional to us pressure.
Mathematically
V ∝ l/p, v = k/p (where k is constant)
K = VP
Let k = k1
Then, if k = k, V and P = V1P1
V1P1 = V2P2

36.2cm3
25.7cm3
72.8cm3
24.3cm3
Correct answer is C
General formular of Gas laws
(P1V1) ÷ T1= (P2V2) ÷ T2
P1 = 800mmHg, V, = 76cm3, Tr = 273 + 27 = 300k
P2 = 760mmHg, V2 = ? T2= 273 + 0 = 273
(800 × 76) ÷ 300 = (760 × V2) ÷ 273
V2 = (300 × 76 × 273) ÷ (300 × 760) = 72.8 cm3
The volume of gas as S.T.P = 72.8 cm3
