A flask of capacity 2 L is heated from ...

A flask of capacity 2 L is heated from `35 C^(@)` to `45 C^(@)`. What volume of air will escape from the flask ?

A

10 mL

B

20 mL

C

60 mL

D

50 mL

Text Solution

Verified by Experts

The correct Answer is:
C
`(V_(1))/(T_(1))=(V_(2))/(T_(2))`
`V_(1)=2 L, T_(1)=35+273=308 K`
`V_(2) = ? , T_(2)=45 +273 = 318 K`
`V_(2)=(2)/(308)xx318=2.06 L`.
Capacity of flask = 2 L
Volume of air escaped `= 2.06 -2 = 0.06 L` or 60 mL
