2. Solvent
3. Drier
4. Extenders

3. The component that holds all the component of paint with surface is called:

1. Binder
2. Solvent
3. Drier
4. Extenders

4. When the binder form bond with the surface by the process of evaporation of solvent system of liquid, paint is called

4. All of the above

7.  Latex paints use which of the following means to form film?

1. Coalescence
2. Chemical bonding
3. Evaporation
4. All of the above

8. Which of the following components is responsible for the “hue” of paint?

1. Pigments
2. Binders
3. Solvents
4. All of the above

9. The term “hue” is associated with which of the following?

1. Mineral constituent of the soil
2. Base color of the soil
3. Texture of the soil

10. Pigments of green color paint are obtained as evidence, what is most predominantly the origin of pigment?

1. Organic
2. Inorganic
3. Semi-Synthetic organic inorganic mixture
4. 50% organic and 50% inorganic

11. Assertion (A): In common paint applications, pigments are expensive so they are adjusted by adding more solvent to paint without losing its color.
Reason (R): Solvent adds opacity, viscosity and hiding ability of paint.

1. (A) is correct, but (R) is incorrect
2. Both (A) and (R) are incorrect
