Tuition Singapore Chemistry Tuition Kinetics Theory of Particles

Common Error 1

Particles in a solid are motionless

Correct Concept 1

Particles in a solid vibrate and rotate about their fixed positions although they do not move from place to place

Common Error 2

During melting, the temperature rises because heat is absorbed.

Correct Concept 2

During melting, the temperature remains constant at the melting point because the heat absorbed is used to overcome the attractive forces between the particles.

Common Error 3

Diffusion does not occur in solids.

Correct Concept 3

Diffusion does occur in solids. In fact, it occurs extremely slowly in solids because the solid particles are less energetic and move with less speed.
