A glass cylinder contains four liquids in four separate layers. One liquid is water. The purple liquid has a density 1.62 g/cm3. The yellow liquid has a density of 0.46 g/cm3. The red has a density of 0.91 g/cm3. What is the order of the liquids in the cylinder? Explain your answer. What will happen if you slip a small, flat, chip of wood (density 0.85 g/cm3) into the cylinder?

Respuesta :

Answer:

  1. The order of the liquids in the cylinder will be yellow liquid, followed by red liquid, water & lastly purple liquid.
  2. The wood is likely to sink in the 1st liquid(yellow) but float on the 2nd liquid(red).

Explanation:

  1. The arrangement of the liquids in the cylinder is determined by their densities. Water has a density of 1g/cm3 & that of the others are stated in the question already. Comparing the liquids densities now, we can easily identify the liquid with the lowest density to that of the highest. The liquids with greater densities will sink while those with lower ones wsill float. In this case, the yellow one has the least density of 0.46g/cm3,followed by the red one(0.91g/cm3),water of density 1.0g/cm3 & coming last, the purple liquid(1.62g/cm3)
  2. The wood has a density of 0.85g/cm3. This will make it denser than the 1st liquid(yellow) so will sink in it but is lower in density than the next liquid so will float on it.

Hope you understand now. I'll appreciate getting brainliest from you if you liked the explanation.
