When egg white is mixed with water and stirred what does it form? Are we able to see path of light through it?

Expert Answer:
Egg white in water forms a colloidal solution.
When we pass a beam of light through a colloidal solution, the path of the light becomes visible when seen from a direction at right angle to that of the incident light.
Usually the particles of size in the range of 10-9 m to 10-6 m scatter the visible light.
This scattering of light by particles in a colloid is known as Tyndall effect.

- Which statement regarding the effect of humidity on evaporation is correct? Humidity has no effect on evaporation. With the increase in humidity, rate of evaporation decreases. With the decrease in humidity, rate of evaporation decreases. Humidity sometimes increases and sometimes decreases the rate of evaporation. pls explain.
