Answer:
the distance by which the height of the liquid in the cylinder change after the ice gets melted = 0.528 cm
Explanation:
The change in volume of glycerin when the ice cube is placed on the surface of the glycerin can be represented as:
Given that ;
the mass of the ice cube (m) = 0.11 kg = 0.110 × 10³ g
density of the glycerine () = 1.260 kg/L = 1.260 g/cm³
Then:
V =
V =
V = 0.0873 L
Now;Initially the volume of the glycerin before the ice cube starts to melt is:
However; the volume of the water produced by the 0.11 kg ice cube =
The expression for change in the volume of glycerin after the ice cube starts to melt is as follows:
replacing with
; we have:
The overall total change in the volume of the glycerin is illustrated as:
Now; from the foregoing ; lets replace the respective value of and
in the above equation ; we have;
The formula usually known to be the volume of a cylinder is :
For the question ; we will have:
making h the subject of the formula ; we have:
replacing 0.0227 L for and the given value of radius which is = 3.70 cm; we have:
Thus ; the distance by which the height of the liquid in the cylinder change after the ice gets melted = 0.528 cm
