States of Matter

• What are the three main states of matter?

  Solids, liquids, and gases
• What are the properties of a solid?

  • Has a definite shape and volume
  • Does not flow
  • Cannot be compressed
• What are the properties of a liquid?

  • Has a definite volume
  • No definite shape
  • Can flow evenly and easily
  • Cannot be compressed
  • Takes the shape of the container
• What are the properties of a gas?

  • Has no definite volume
  • No definite shape
  • Can flow easily
  • Can be compressed
  • Takes the volume of the container
• How does the shape and volume of a solid differ from that of a gas?

  A solid has a definite shape and volume, while a gas has no definite shape or volume
• If you were to pour a liquid into a container, what would happen to its shape?

  It would take the shape of the container
• Why can gases be compressed while solids cannot?

  Gases have particles that are far apart, allowing them to be compressed
• What is the defining characteristic of a liquid regarding its shape?

  A liquid has no definite shape
• Can a solid flow?

  No, a solid does not flow
• How does the volume of a gas compare to that of a solid?

  A gas has no definite volume, while a solid has a definite volume
• What happens to the volume of a gas when it is placed in a container?

  It takes the volume of the container
• How do the properties of liquids and gases compare in terms of flow and compression?

  Both can flow easily, but only gases can be compressed
• What is an Atom?


  The atom is the smallest particle of a material or substance.
• All material is made up of about 100 different kinds of atom.
• All these atoms can be found in the periodic table of elements.
• What are elements?


  A substance made up of only one type of atom.
• Steel is made up of more then one type of atom, so it is not an element.
• What are all substances made up of?

  Atoms
• What is a substance made up of only one type of atom called?

  Element
• How many different elements are there approximately?

  One hundred
• Where are elements shown?

  Periodic table
• What type of substances make up most of the elements in the periodic table?

  Metals
• What are the three states of matter discussed in the study material?

  Solids, liquids, and gases
• How can the different properties of solids, liquids, and gases be explained?

  By the Particle Model
• What are all substances made up of according to the Particle Model?

  Particles
• Why can't particles be seen with the naked eye?

  Because they are too small
• What is the nature of the attraction between particles?

  Some particles are attracted strongly, while others are attracted weakly
• What type of energy do particles possess?

  Kinetic energy
• What effect does temperature have on the kinetic energy of particles?

  The kinetic energy of the particles increases with temperature
• What are the models of solids, liquids, and gases based on the Particle Model?

  • Solid: Particles are closely packed and vibrate in place.
  • Liquid: Particles are close but can move past each other.
  • Gas: Particles are far apart and move freely.
• How are particles arranged in a solid?

  Particles in a solid are packed tightly in rows close together.
• What type of attraction exists between particles in a solid?

  Particles in a solid attract each other strongly.
• How do particles in a solid move?

  They only vibrate in the same position and do not move around.
• What is the kinetic energy level of particles in a solid?

  Particles in a solid do not have a lot of kinetic energy.
• How are particles arranged in a liquid?

  Particles in a liquid are arranged randomly with gaps between them and are loosely packed.
• How do particles in a liquid move?

  Particles in a liquid can move around slowly.
• What is the attraction level between particles in a liquid?

  Particles in a liquid have less attraction compared to solids.
• What is the kinetic energy level of particles in a liquid?

  Particles in a liquid have a little more kinetic energy than those in a solid.
• How are particles arranged in a gas?

  Particles in a gas are in a completely random arrangement with large gaps between them.
• What is the attraction level between particles in a gas?

  There is hardly any attraction at all between particles in a gas.
