The particle theory Flashcards
What is matter?
Matter is anything that has a mass and volume takes up space. It is everything around us such as close, and even people are made out of particles.
Who discovered what matter was?
This was discovered by Greek philosopher Democritus around 430 BC
What is a postulate?
Calculates are an assumption that is assumed to be true without any evidence
What is the particle theory mostly made up of?
The particle theory of matter is made up of several postulates
What is the first rule in the particle theory?
All matter is made of particles. Matter consists of tiny particles that are too small to see with the human eye. These particles can be individual atoms or groups of atoms known as molecules.
What is the second rule of the particle theory?
All particles are in constant motion. Particles of matter are constantly moving. This can be seen in the states of matter where solid particles vibrate, liquid liquid particles, flow, and gas particles fly around each other.
What is the third rule in the particle theory?
All particles of one substance or identical. All particles of the same substance or identical. Each element is made up of identical particles of matter called atoms.
What is the fourth rule of the particle theory?
Temperature affects the speed at which particles move. Heat causes particles to buy it quickly and act differently. These molecules gain energy as a heat up. As a result, particles move faster and collide, resulting in more distance between them. Lower temperatures, however, slow the movements of these particles and decrease the space between them for example, if you freeze water, it movements will slow down and become solid ice, but it will move faster if you play heat and boil the water making it become water vapor
What is the last rule of the particle theory?
There are spaces between particles. Particles of matter are drawn to one another via intermolecular forces of attraction which variance strength. The attraction between solid molecules is quite strong, which keeps the particles closely back together, resulting in very little space between the particles.
How many rules are there in the particle theory?
