Question 27

What is the particle model of matter?

Answer 27

• All substances are made of tiny particles.
• All pure substances are the same. Different pure substance, different particles.
• Particles have space between them.
• Particles are always in motion.The speed of particles increases/decreases as the temperature increases/decreases-Particles in a substance are attracted to one another. The strength of the attractive force depends on the type of particle.
