A one litre flask contains certain quantity of mercury. If the volume of air inside the flask remains the same at all temperatures then the volume of mercury in the flask is (volume expansion coefficient of mercury is 20 times that of flask)

A

100 cc

B

50 cc

C

200 cc

D

150 cc

Text Solution

Verified by Experts

The correct Answer is:
B
`V xx alpha_(f) = V. xx alpha_(Hg)`
`rArr V. = (1000)/(20) = 50 c c.`
