Matter

Define Matter. Why is it hard to completely define it?

• Matter is nonliving things that take up space and has mass. For a good definition you need to define mass and space, but neither of which is completely definable.

• Matter is anything that occupies space and has mass. For a good definition you need to define mass and space, but neither of which is completely definable.

• Matter is only living things that takes up space and has mass. For a good definition you need to define mass and space, but neither of which is completely definable.

• Matter is large items. Matter is not really defined because there is too much to describe it.

Contrast pure substances and mixtures.

• Pure substances are made of several kinds of substances. Mixtures are made of one kind of substance, all the way down to the particle level (uniform in composition).

• Pure substances are made of several substances, all the way down to the liquid form. Mixtures are chemical combinations of two or more substances.. The parts of mixtures can not be separated by physical methods, such as filtering or evaporating

• Pure substances are made of one kind of liquid, all the way down to the particle level (uniform in composition). Mixtures are subatomic combinations of two or more substances in a changeable composition. The parts of mixtures cannot be separated by physical methods, such as filtering or evaporating

• Pure substances are made of one kind of substance, all the way down to the particle level (uniform in composition). Mixtures are physical combinations of two or more substances in a changeable composition. The parts of mixtures can be separated by physical methods, such as filtering or evaporating

What main factor determines a material's state of matter? How does it affect the particles of a substance?

• Temperature. It affects the motion of particles.

• Force. Determines the size of the object.

• Movement. Changes the makeup of the atoms

• Friction. It affects the shape of the particles

What are the differences in the motions and arrangements of particles in solids and liquids? Between liquids and vapor?

• Particles in solids are far apart and move very fast, while particles in liquids are mobile, though still close together. Particles in gas state vibrate in fixed positions compacted close together.

• Particles in solids vibrate in fixed positions compacted close together, while particles in liquids are mobile, though still close together. Particles in gas state are far apart and move very fast.

• Particles in solids are mobile, though still close together, while particles in liquids vibrate in fixed positions compacted close together. Particles in gas state are far apart and move very slow.

• Particles in solids are mobile, though still close together, while particles in liquids are far apart and move very fast. Particles in gas state vibrate in fixed positions compacted close together.

How is the plasma state of a substance different from the gas of the same substance?

• Particles in both plasmas and gases are close together and move very slow, but the particles in plasmas collide so hard that they break apart and become electrically charged.

• Particles in both plasmas and gases are far apart but move very slow, but the particles in plasmas collide so hard that they break apart and become electrically charged.

• Particles in both plasmas and gases are far apart and move very fast, but the particles in plasmas collide so hard that they break apart and become electrically charged.

• Particles in both plasmas and gases are close together and move very fast, but the particles in plasmas collide so hard that they break apart and become electrically charged.
