What is matter made up of? |
Small discrete particles |
|
|
What does the particulate mature of matter says? |
The 'Brownian Motion' is the motion of tiny particles suspended in a liquid or gas. It can be observed using a microscope. |
|
|
What does Brownian motion show? |
Smoke particles are observed to be moving in a random manner. this is due to the random collisions between air particles and smoke particles. |
|
|
Using the KPT, what is the arrangent of particles in a solid? |
The particles are closely packed in an orderly manner |
|
|
Using the KPT, what is the arrangement of particles in a liquid? |
The particles are closely packed in a disorderly manner |
|
|
Using KPT, what is the arrangement of the particles in a gas? |
The particles in a gas are very far but in a disorderly manner |
|
|
using the KPT, What is the particle movement in the solid? |
The particles in a solid vibrates about their fixed position |
|
|
Using the KPT, what is the particle movement in liquids? |
The particles move freely by sliding over one another |
|
|
Using KPT, what is the particle movement for gases? |
The particles move randomly at high-speed in all directions over long distances Gas has the most kinetic energy. |
|
|
Describe the forces of attraction between solid, liquid and gas |
The forces of attraction is the strongest for solid followed by liquid and gas |
|
|
What happens when matter expands? |
The particles gain kinetic energy and move further way from each other |
|
|
What happens when matter expands? |
The particles gain kinetic energy and move further way from each other |
|
|
What happens when matter contracts? |
The particles will lose kinetic energy and move closer to each other |
|
|
Why does the mass of the object remain the same even when it contracts or expands? |
Mass is the amount of matter in the object. The amount of matter in the object remains the same. |
