Question

What is particle theory?

Answer 1

Particle theory:

• It describes the microscopic properties of atoms (or molecules) and their interactions, which result in observable macroscopic properties (such as pressure, volume, and temperature).

Postulates:

• All matter is made up of tiny particles known as atoms.
• Particles of matter are constantly in motion.
• Particles of matter attract each other.
• The Particles of matter have space between them.
• Atoms of the same element are essentially identical and atoms of different elements are different.
• The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
• As temperature increases, particles of matter move faster.
