Question

Water at 40C is filled to the brim of 2 beakers. A boy performed an experiment A of heating and B of cooling. The observation was :


  1. water level in B went down and in A water flowed out
  2. water flowed out in both the cases
  3. water level went down in both cases
  4. water flowed out in B and water level went down in A

A
water flowed out in both the cases
B
water flowed out in B and water level went down in A
C
water level went down in both cases
D
water level in B went down and in A water flowed out
Solution
Verified by Toppr

Water expands when heated from 40C onwards.
Since water expands in both the cases, it will overflow from both experiments A and B.
