Solution
The correct option is D Flask D
Liquids tend to expand when their temperature increases, this expansion of a liquid on being heated is called thermal expansion of the liquid. For example, the same mass of boiling water occupies more volume at 100 ∘C than at 20 ∘C.
Since, Flask D attains the highest temperature of 85 ∘C so it will contain the highest water level.
