A glass flask of volume one litre at 00C is filled, level full of mercury at this temperature. The flask and mercury are now heated at 1000C. How much mercury will spill out, if coefficient of volume expansion of mercury is 1.82 × 10–4/0C and linear expansion of glass is 0.1 × 10–4/0C respectively –
A
21.2 cc
B
15.2 cc
C
1.52 cc
D
2.12 cc
Answer
15.2 cc
Explanation
Solution
DVA = DVR – DVs
= V (rA – rs) Dq
= 103 c.c. (1.82 × 10–4 – 0.3 × 10–4) × 100
= 1.52 × 10 cc = 15.2 cc
