• Matter consists of small particles.

• The particles are in constant movement.

• Particles can change of state except to plasma.

• There is an empty space between particles.

Temperature is the meassurement of:

• electric energy

• kinetic energy

• hidraulic energy

• heat energy

When two bodies have the same temperature this means they have a thermal ________________.

Chemical changes:

• Can´t be reversed.

• Can´t be heated.

• Can´t be modified.

• Can´t be fixed.

Condensation is the process where the gas turns into:

• gas

• plasma

• ice

• water

We can say that plasma is the first state of matter because:

• 98% of thing in the universe is plasma.

• 91% of thing in the universe is plasma.

• 90% of thing in the universe is plasma.

• 99.9% of thing in the universe is plasma.

Plasma is formed when gas is exposed to _____________ temperature.

When the atoms of the gas are heated, they lose the

• atoms

• electrons

• protons

• neutrons

The free electrons give the plasma a charge, making it to conduct:

• energy

• static

• electricity

Which of the following is NOT in plasma state:
