Kinetic energy of particles
High
Change of state
Energy is taken in
Melting
Solid to liquid
Boiling
Liquid to gas
Energy released
Freezing
Liquid to solid
Condensation
Gas to liquid
Sublimation
Gas to solid
Using Kinetic particle theory to explain the change in state
Particle gain or lose energy
Change in the movement of particles
Change in the position of particles
Heating curve
Link Title
Temperature remains constant during melting and boiling as heat energy is used to overcome the attractive forces of attraction
As the solid is heated, particles in solid gain kinetic energy and the temperature of the solid increases until it reaches at a melting point
Melting occurs at a fixed temperature. Energy from heating is used to overcome forces of attraction between the particles. A mixture of solid and liquid exists and do not gain kinetic energy
All the solid is melted and temperature rises as heating continues. Liquid particles gain kinetic energy
Cooling curve
Link Title
Particles in liquids lose kinetic energy. The temperature of the liquid drops to freezing point
A mixture of liquid and solid exists and the temperatures remain constant. This is due to the heat energy is releases when particles of liquid slow down to take up fixed and orderly positions in the solid state
