Matter is everything that has ___________ and occupies _______________.

• motion - matter

• mass - space

• space - volume

• mass - particles

particles are attracted by __________________

• empty space

• movement

• force

Look at the picture and complete.

Particles of ____________________ state.

• liquid

• gas

• solid

The force of attraction between the particles is weaker, so they are able to move more freely.

• Liquid particles

• Solid particles

• Gas particles

Look at the picture.

These particles have more kinetic energy, so they are farther apart and they occupy all available space.

• Solid

• gas

• Liquid

• Heat

• Thermometer.

• Scale

Kelvin, Fahrenheit and Celsius are ___________________________

• Volume scales

• Mass scales

• Temperature Scales

____________________ corresponds to the measurement of kinetic energy of particles.

• Temperature.

• Thermal equilibrium.

____________________ is the transfer of energy from a body with a higher temperature to one with a lower temperature.

• Temperature

• Heat

• Thermal equilibrium

When both bodies reach the same temperature, this is called ___________________________________.
