Changing States of Matter

Which of the following is incorrect about solid?

• Strong forces of attraction holds the particles close together

• The particles of solid can move slightly

• Solid has regular lattice structure

• Solid has definite shape and volume

What happens when solid is heated?

• The particles lose some energy so that they will vibrate more

• The particles lose some energy so that they will vibrate less

• The particles gain more energy so that they will vibrate more

• The particles gain more energy so that they will vibrate less

Which of the following doesn't happen when the liquid is heated?

• The particles lose its kinetic energy

• The particles gain more energy

• The particles move around faster

• The intermolecular forces getting weaker

What is the name of the point which refers to the temperature when liquid changes into gas?

• Freezing point

• Melting point

• Boiling point

• Vapor point

What does it mean by "the particles of gases are constantly moving with random motion"?

• The particles move in straight line

• The particles are very free to move

• The particles have very weak force of attraction

• The particles are moving in any direction

What will happen if the gas particles get more energy from heating up?

• The gas particles will move more randomly and they are all will expand in any container

• The gas will either expand if the container is expandable like a balloon or either the container is fixed, then the pressure will increase

• Both energy and pressure of the particles will increase so that it makes the gas easier to explode

• The gas will reach its maximum kinetic energy

What is the name of the process when the gas changes into liquid?

• Boiling

• Vaporisation

• Sublimation

• Condensation

Which of the following correctly describes the melting process?

• The energy wont change at all even though the particles are getting closer

• The particles will get more kinetic energy to set the particles free

• The particles wont have enough energy to overcome the attraction

• The particles will get more energy to break the bond

What is the difference between the force of attraction in liquid and gas?

• Force of attraction in gas is very weak, as for in liquid is just weak

• Force of attraction in liquid is weaker than that in gas

• Both gas and liquid have similar forces of attraction

• Force of attraction in gas doesn't change when it turns into liquid

The particle model of of states of matter isn't perfect. Which of the following doesn't explain this statement correctly?

• The model doesn't include details of the forces between particles

• In reality, the matters are exist in atoms, ion or molecules

• In reality, matters are not solid, inelastic, and spheres

• The model cannot explain about the ability of each state of matter to have definite shape and occupy volume
