Answer: Tyndall effect

Explanation:

Colloids are defined as the mixtures where the size of the particle is within the range of 2nm to 1000 nm. In these mixtures, physical boundary is seen between the dispersed phase and dispersed medium.

Tyndall effect is defined as the effect in which scattering of light takes place by the particles present in a colloid or in very fine suspension. For Example: Scattering of sunlight by clouds

Brownian motion is the movement of finely suspended colloidal particles due to collisions.

Mohs is a scale used to determine the hardness of materials

Faraday is a law which states that the mass of the substance deposited at any electrode is directly proportional to the quantity of electricity or charge passed.

Water has a specific heat of 4.186 J/g*C. How much energy would be required to raise the temperature of 10 g of water by 10 C?

Sladkaya [172]

Energy(heat) required to raise the temperature of water : 418.6 J

<h3>Further explanation </h3>

Heat can be calculated using the formula:

Q = mc∆T

Q = heat, J

m = mass, g

c = specific heat, joules / g ° C

∆T = temperature difference, ° C / K

Specific heat of water = 4.186 J/g*C.
