Question

4. A measuring cylinder contains water up to the level 40 mL. The water level rises to 70 mL when a ring is put into it. If the mass of the ring is 51 g, Calculate the density of ring. on water. Give reason.​

Answer 2

Explanation:

initial level of water = 40 ml

final level of water = 70 ml

change in volume = 70ml - 40ml = 30 ml

volume of ring = 30 ml

= 30 cm^3 (1ml = 1 cm^3)

density of ring = mass of ring / volume of ring

51/30 = 17/10

= 1.7 g/cm^3

Reason

when the ring is immersed in the cylinder filled water, the water level rises up

when the solid is removed, the water level will fall to as it was before the solid is immersed

this show that when a solid is immersed it pushes water upwards by occupying the space of water

it can be concluded that all solids occupy space...
