Question

A certain mass of gas occupies a volume of 300 cc at 27 ℃ and 620 mm pressure. The volume of this gas at 47 ℃ and 640 mm pressure will be, 400 cc, 510 cc, 310 cc, 350 cc

MARKS App · Accepted Answer

Given initial volume V 1 = 300 c c ; initial temperature T 1 = 27 ℃ = 300 K , initial pressure p 1 = 620 m m , final temperature T 2 = 47 ℃ = 320 K and final pressure p 2 = 640 m m . We know from the general gas equation p 1 V 1 T 1 = p 2 V 2 T 2 = 620 × 300 300 = 640 × V 2 320 = 310 c c w h e r e , V 2 i s t h e f i n a l v o l u m e o f t h e g a s
