Kinetic Particle Model

Question 1

Kinetic Particle Model

Answer 1

states that the small particles (atoms or molecules) that make up all matter have kinetic energy. Therefore all particles are in constant motion, even in extremely cold solids (until absolute zero).

Question 2

Model

Answer 2

a representation that describes or explains the workings within an object, system or idea.

Question 3

Assumptions of kinetic particle model

Answer 3

• All matter is made up of very small particles (atoms or molecules).
• The particles are in constant motion.
• Overall, no kinetic energy is lost or gained during elastic collisions between particles.
• There are forces of attraction and repulsion between the particles in a material.
• The distances between particles in a gas are large compared with the size of particles.

Question 4

Absolute zero

Answer 4

A point at which the particles would eventually stop moving. (0K = -273.15°C)
