Basics of the Kinetic Particle Theory that Students can Learn from Chemistry Private Tuition in Singapore

If your child is weak in Chemistry, it is best to engage a tutor from a private tuition Singapore agency. An experienced tutor will know how to identify the weak Chemistry topics your child is facing, and help him or her to improve in those topics. One of the first topics that most tutors will go through is the Kinetic Particle Theory. Let’s look at some of the basic concepts of the topic that tutors will go through with students. 

Introduction To Matter

Matter is anything that has mass and occupies space.
 Matter can exist as a solid, liquid or gas. 
For example, a soccer ball, Coke in a can, halal hotel singapore, and air in an empty syringe
. These three forms are called the states of matter.

Kinetic Particle Theory

The kinetic particle theory is used to explain the difference in the properties of solids, liquids and gases. The kinetic particle theory suggests that all matter is made up of small discrete particles, and these particles are in constant and random motion. The kinetic particle theory can also be used to explain the states of matter
 and the changes of state

Properties Of Solids 

Solids have fixed/ definite volume, cannot be compressed
, fixed/ definite shape
, cannot flow and have high density.
 The particles in solids are in a fixed and regular/ orderly arrangement
. Hence solids have a fixed shape and cannot flow
. Solid particles

 are packed very closely together, and therefore solids have a fixed volume and high density.
 The forces of attraction between particles

 are very strong, and the particles can only vibrate about their fixed positions
. In addition, the particles have the least amount of energy compared to liquids and gases

Properties Of Liquids 

Liquids have fixed/ definite volume, cannot be compressed
, but they have no fixed/ definite shape
, so they take the shape of the container they occupy. On top of that, liquids can flow and have high density.
 The particles in liquids have no fixed, regular (disorderly) arrangement
 and hence they have no fixed shape and can flow
. Their particles are still packed quite closely together but slightly further apart than in solids. As such, liquids have fixed volume and high density
. The forces of attraction between liquid particles

 are strong but again, not as strong as solids
. Liquid particles also vibrate like solid ones, but they can change their positions, and are able to slip and roll over one another randomly
. Finally, liquid particles have more energy than solid particles, but less energy than gas particles.

Properties Of Gases 

Gases have no fixed volume, can be compressed
, have no fixed shape, and will completely fill up and take the shape of their containers.
 Moreover, gases can flow and have low density
. Like liquid particles, gas particles have no fixed, regular (disorderly) arrangement
 and hence they have no fixed shape and can flow
. Gas particles are very far apart from one another, and there are 
lots of empty spaces between particles
. Therefore, gases have no fixed volume, low density and can be compressed.
 In addition, there are negligible (almost none) forces of attraction
 between gas particles, and they can move freely and randomly in all directions at high speeds, occupying any available spaces. Notwithstanding, gases have the most energy among all states of matter.
