How did convection currents cause the plates to move

Chemistry
1 answer:
Paul [167]3 years ago

Convection currents in the mantle are powered by the heat from the earth's core. The convection cells move in a circular motion in the mantle as the plumes or currents of magma rises and falls due to heating and cooling. This circular motion will affect the base of the crust and drag the crustal plates along. The movement however is very slow, as plates only move a few centimeters or inches per year.

Which solution has the lowest freezing point?
Leokris [45]
<span>Correct Answer: Option 3 i.e. 30 g of KI dissolved in 100 g of water.

Reason:
Depression in freezing point is a colligative property and it is directly proportional to molality of solution.

Molality of solution is mathematically expressed as,
Molality = </span>\frac{\text{Number of moles}}{\text{Weight of solvent (Kg)}}<span>

In case of option 1 and 2, molality of solution is 0.602 m. For option 3, molality of solution is 1.807 m, while in case of option 4, molality of solution is 1.205 m.

<u><em>Thus, second solution (option 2) has highest concentration (in terms of molality). Hence, it will have lowest freezing point</em></u></span>
