solid, liquid and gas

• Describe the movement of particles in a solid?

  atoms vibrate around a fixed point
• In which state of matter do particles have the most energy?

  gas
• What type of energy do particles have that is related to movement?

  kinetic
• Explain how particles move differently when the temp increases?

  their kinetic energy increases and they move faster
• Compare the difference in forces between particles in three states of matter?

  in solids, there are the strongest forces between particles. Liquids have weaker forces between particles, and gases have no forces between particles
• In which state(s) of matter do particles move freely and randomly?

  liquids and gases
• What are the differences between the arrangement of particles in liquids and gases?

  in liquids there are still held close together. In gases there are no forces, so they are all far from each other
• What are the differences between the arrangement of particles in liquids and solids ?

  In solids there are stronger forces between particles, so they cannot move freely. They vibrate. In liquids there are weaker forces so the particles can move freely and randomly
• What happens to particles in a solid to cause the state to change to a liquid?

  as the temp increases, particles gain kinetic energy and vibrate faster. This causes bonds to weaken until the particles are able to move freely and randomly.
• What happens to particles in a gas to cause the state to chnage to a liquid?

  As the gas cools, the particles lose kinetic energy and move more slowly. Forces start forming between particles, holding them together to form a liquid.
• Is bondbreaking endo or exothermic ?

  endothermic = gives out energy to the surroundings
