Question

Based on the H_2O phase diagram, identify the significance of point (0.01 degree, 0.006 atm) and point (374 degree C, 218 atm) melting point & boiling point melting point & critical point Triple point & boiling point triple point & critical point Which is not collagitive property solution? vapor pressure lowering osmotic pressure boiling point elevation and freeting point depression Tyndall Effect Which statement is incorrect in terms of the colloid? colloid is the heterogenous mixture colloid contains particles larger enough to scatter the visible light. colloidal particles do not change speed & direction erratically.

Explanation / Answer

All are answers you roundedoff are correct.

(3) (d) Melting point 0 degree at 1 atm, boiling point 100 degree at 1 atm.

(4) (d) Tyndal effect is the property of colloids whcih explains about the scattering of light. It does not depend on the nuber of solute paicles. Hence not colligative property.

(5) (d) Colloid particles move randomly in all the directions, hence their speed wil change.
