Properties of Matter Quiz

The particle model explains the properties of solids, liquids, and gases mainly on the basis of:

• Particle color

• Particle mass

• Particle arrangement and movement

• Particle charge

Why does a liquid take the shape of its container but a solid does not?

• Liquids have fixed shape but fixed volume

• Liquids have weak particle attraction and can flow

• Solids have no particle attraction

• Liquids expand when cooled

Which of the following is a physical change?

• Burning wood

• Rusting iron

• Melting ice

• Cooking egg

The process in which a solid changes directly into gas without becoming liquid is called:

• Condensation

• Sublimation

• Deposition

• Evaporation

When a gas is compressed in a syringe, what happens to its particles?

• They shrink in size

• They stop moving

• They move closer together and collide more often

• They change into solid particles

Why does evaporation cause cooling?

• Because particles gain heat from surroundings

• Because only high-energy particles escape, lowering average energy

• Because it converts kinetic energy to potential energy

• Because gas exerts pressure

Which statement best explains why gases are compressible?

• Gas particles are charged

• Gas particles are far apart with lots of empty space

• Gas particles stick together strongly

• Gases have lower density than liquids

The boiling point of liquid nitrogen is –196 °C. At –200 °C, nitrogen exists as:

• Gas only

• Solid only

• Both solid and liquid

• Liquid only

What happens to the average kinetic energy of particles when a substance is heated?

• It decreases

• It remains the same

• It increases

• It first decreases, then increases

In a heating curve, during melting, the temperature:

• Increases rapidly

• Remains constant

• Decreases slowly

• Drops suddenly
