Identify which properties could correspond to solids, plasmas, or both. maintain a unique shape. collide infrequently with other particles. have very high velocities. conduct electricity. protons. have a low temperature. has long-range order.

Explanation:

A plasma is often described as the fourth state of matter and it exists beyond gases. It forms when gases have been heated to a very high temperature and their electrons becomes free and it leaves behind an electrified nucleus and free electrons.

A solid is a state of matter in which atoms are packed closely together and are held by a very strong attractive forces.

Plasmaparticles collide infrequently with other particles.  

Due to their free nature, particles of plasma collides infrequently and randomly with one another. They behave like gases in this regard.

Plasmaparticles have very high velocities.  

Particles of plasma due to their kinetic energy and their freedom have very high velocities.

Both can conduct electricity.  

Plasmas due to ionic form and the presence of free electrons can conduct electricity. Metals which are solids contains free mobile electrons and also conducts electricity.

Bothcontain protons.  

All matter have the atom as their building blocks. Atoms are made up of subatomic particles of protons, neutrons and electrons.

Solidstypically have a low temperature.  

Of all the different states of matter, solids occur at the lowest temperature.

Solidsstructure has long-range order.

Solids have a very long range order and their atoms have a very consistent arrangement over their length.

Explanation:

Plasma  is defined as the state of matter which is a hot ionized gas that consists of positively charged ions and negatively charged electrons.

Like gases, particles of a plasma are also held by weak forces that are Vander waal forces. And, as it is a hot ionized gas therefore, particles of plasma move rapidly from one place to another.

In a solid, molecules are held together by strong intermolecular forces of attraction. As a result, they are unable to move from their initial place but they can vibrate at their mean position.  

Hence, in solid substances the molecules have low kinetic energy. Also, molecules in a solid are placed in a long range order.

Solids like copper, silver etc able to conduct electricity.

Also, both plasma and solids contain proton because every atom contains neutrons, protons and electrons.

Thus, we identify the properties corresponding to solids, plasmas, or both are as follows.

Solids maintain a unique shape.Plasma particles collide infrequently with other particles.Plasma particles have very high velocities.Both can conduct electricity.Both contain protons.Solids typically have a low temperature.Solids structure has long-range order.

Answer is: solid is the state in which matter has a definite shape and volume.There are two types of solids:crystalline (solids that have a very orderly, 3-dimentional arrangement of atoms or molecules) and amaorphous (composed of atoms or molecules that are in no particular order). 
Plasma is is the state of matter that does not have a definite shape or volume. Plasmas and some solids (metals) conduct electric current.
