• Indefinite volume and a definite shape.

In which state of matter are particles packed tightly together in fixed positions?

• Gas

• Solid

• Liquid

• Plasma

The state of matter in which particles are arranged in either a crystalline or an amorphous form is

• Liquid

• Solid

• Gas

• Plasma

Particles of a liquid

• Are tightly packed together and stay in a fixed position

• Have no viscosity

• Decrease in volume with increasing temperature.

• Are free to move in a container but remain in close contact with one another

In which state of matter do the particles spread apart and fill all the space available to them?

• Plasma

• Liquid

• Solid

• Gas

The change from liquid to solid, or the reverse of melting, is called

• Condensation

• Boiling

• Sublimation

• Freezing

The freezing point of water is the same as its

• Melting point

• Boiling point

• Sublimation point

• Evaporation point

What is vaporization?

• Gas becoming liquid

• Liquid becoming solid

• Gas becoming solid

• Liquid becoming gas

Which state of matter undergoes changes in volume most easily?

• Solid

• Liquid

• Gas

• Plasma

The greater the speed of gas particles in a container, the

• fewer collisions there will be

• lower the temperature.

• greater the pressure.

• lower the pressure
