Question

Water at 4°C is filled to the brim of two beakers of glass of negligible coefficient
of expansion. A boy performed an experiment of heating the beaker (A) and
cooling the beaker (B). The observation he makes will be:
level of water in (B) goes down and the water in the beaker (A) overflows
water overflows in both (A) and (B)
water overflows in the beaker (B) and water level goes down in beaker (A)
water level goes down in both (A) and (B)​

Answer 1

Answer:

level of water in (B) goes down and the water in the beaker (A) overflows

Explanation:

as water in A will expand on heating and water in B will contract on cooling
