Question

With increase in temperature, Match the following two columns.

Answer 1

(A) Density of water is highest at 4 degree therefore, it will increase when temperature increases from 0 to 4 and decreases after that.
A->4
(B)Since water's density ,may increase or decrease therefore, fraction of solid floating in a liquid depends on density of water therefore, it can increase or decrease.
B->4
(C)Apparent weight of solid immersed in water depends on the density of water therefore, it can also may increase or decrease.
C->4
(D)When temperature is increased length of the material of which pendulum is made will increase and since $T=2\pi \sqrt{L/g}$ therfore, T increases.
D->1
