​Objectives:

1. Describe the particle Model of Matter

2. Illustrate the arrangement of particles in the three states of matter

3. Use the particle model of matter to explain the properties of solids, liquids and gases​

Some text here about the topic of discussion

Let's Try ​

PRE-ASSESSMENT ​

Multiple Choice

Particles have spaces in between them. These spaces are filled with _________.

• Air

• Anything

• Nothing

• Oxygen

Multiple Choice

Which is TRUE about LIQUIDS?

• The particles are very far from each other.

• The particles can vibrate and move randomly.

• The particles are quite closely packed together and in constant motion.

• The particles are arranged in a fixed or ordered manner.

Multiple Choice

Solids have a fixed shape and volume becuase the particles are held tightly together due to a very strong attraction between them.

• TRUE

• FALSE

Multiple Choice

Which explains why 500 mL of alcohol mixed with 500 mL of water yielded 975 mL of solution.

• Water molecules reacted with the particles of alcohol thereby decreasing the volume of the solution.

• Water molecules can fit the spaces between the larger alcohol particles thereby decreasing the volume of the mixture.

• The particles of the mixture reacted easily making the volume of the solution lesser than the reactants.

• The alcohol is ver volatiile, this means that the particles immediately evaporated upon mixing with water.

Multiple Choice

Which of the following is a property of gases?

• Compressible

• Incompressible

• Non-fluid

• Definite Shape

Multiple Choice

Which of the following statements is TRUE of the particle nature of matter?

• The particles of matter are 100,000x larger than the size of human hair.

• The space in between the particles is the same for all phases of matter.

• Matters are made up of tiny particles too small to be seen with the naked eye.

• Attractive forces are the same for all phases of matter.

Multiple Choice

The particles are in constant motion. This motion is related to the kinetic energy of particles.

• TRUE

• FALSE

Multiple Choice

Based on the Kinetic Molecular Theory (KMT) of gases, the average kinetic energy of gas particles depends on the temperature of the gas. The kinetic energy of any moving object, including a particle , is given by the following equation.  

• $$KE\ =\ \frac{1}{2\ }mv^2$$  

• $$PE\ =\ mgh$$  

• $$V=\frac{k1}{p}$$  

• KE=PE

Multiple Select

Which of the following properties can be attributed to the strong attractive forces between the particle nature of matter?

• Very High compressibility of gases

• Surface Tension

• Capillary action

• Random motion

Multiple Select

Why do liquids have definite volume even if it takes the shape of its container?

• The particles of liquids are closely arranged together even though it is not in an orderly manner.

• The kinetic energy is strong enough to counter-effect the attractive forces in between the particles.

• The molecules move freely.

• The molecules are very far apart from each other.

Multiple Select

The three types of Inter-molecular forces which are responsible for making solids have relatively fixed positions with only vibrational movement.

• Dipole-Dipole attractions

• London Dispersion

• Hydrogen Bonding

• Lone pairs
