Chemistry Flashcards
What are the distinguishing properties of solids?
Has a fixed shape, cannot be compressed and has a fixed volume.
What are the distinguishing properties of liquids?
No fixed shape, can be compressed, has no fixed shape
What are the distinguishing properties of gases?
No fixed shape, can be compressed, has no fixed shape, particles not bound together.
Describe the structure of solids in terms of particle separation, arrangement and types of motion.
Particles in a solid are joined by chemical bonds. They have a fixed arrangement and vibrate around a fixed point.
Describe the structure of liquids in terms of particle separation, arrangement and types of motion.
Particles in a liquid are joined by weaker chemical bonds than solids. They do not have a fixed arrangement and particles flow.
Describe the structure of gases in terms of particle separation, arrangement and types of motion.
Particles in a gas are unbound and free. They are able to move about randomly.
What is the name of the change of state from solid to liquid?
melting
What is the name of the change of state from gas to liquid?
condensation
What is the name of the change of state from gas to solid?
deposition
What is the name of the change of state from liquid to solid?
freezing
What is the name of the change of state from liquid to gas?
evaporation
What is the name of the change of state from solid to gas?
sublimation
What happens to the particles when boiling?
Liquid particles can overlap and move past one another but remain bonded together. As more energy is supplied, bonds break and particles are free to escape.
What happens to the particles when condensing?
Gas particles move freely, quickly and randomly. As energy is lost, the particles slow down, eventually reforming chemical bonds with one another.
