Q1.What is diffusion?

The movement of particles from an area of lower concentration to an area of higher concentration The movement of particles from an area of higher concentration to an area of lower concentration The movement of solutes in a solvent The movement of particles from one area to another

1/8

Q2.In which states of matter are particles randomly arranged?

Solid and liquid Liquid and gas Gas and solid

2/8

Q3.In which states of matter can diffusion happen?

Solid and liquid Liquid and gas Gas and solid

3/8

Q4.Why can't diffusion happen in solids?

Because the particles are in a fixed position Because the particles move around too quickly Because the particles are only able to move around each other Because the particles are moving around in all different directions at different speeds

4/8

Q5.Which of the following factors does NOT affect the rate of diffusion?

Temperature Surface area Thickness of diffusion pathway pH

5/8

Q6.What will an increased temperature do to the rate of diffusion?

Decrease it Increase it Nothing, the rate will stay the same

6/8

Q7.Which of the following is a property of solids?

High density Low density Can flow Can change shape to fill container

7/8

Q8.What is a solute?

The substance that does the dissolving The substance that is dissolved A substance that can move from a low to high concentration A mixture of a solvent and a solution together
