The coefficient of volumetric expansion of a block of mass is A
the desinty of the block at room temperature is D
density of a liquid is 2D at room temperature
The coefficient of volumetric expansion of the liquid is B
Find the fraction of mass that will be inside the liquid at temperature T

24i am getting diff...
final fraction immersed =f =1/2 (1+(B-A)ΔT)
where ΔT=T-Troom
is it correct sir???????? i got it after writing 2 pages!!!!if correct then only i will shorten it up and post ....plz reply
3at room temperature ..........
DVg = V(SUB)2Dg.........
V(SUB)/V = 1/2.........
NOW AS TEMP. INCREASES NEW DENSITY OF BLOCK IS.......
D/(1+ A(T-T(ROOM)) ........
DENSITY OF LIQUID.....
2D/(1+ B(T-T(ROOM))........
V(SUB)/V = (1+ B(T-T(ROOM))/2(1+ A(T-T(ROOM)) ....
