Which substance is an example of plasma? question 3 options: air blood lightning wood
question 4 solids, liquids, and gases are the only states of matter. question 4 : true false
question 5 most of the matter in the universe is made out of which state of matter?
question 5 gas liquid solid plasma

Q 3 = lightning

Q 4 = False because there is also a fourth state of matter which is called plasma.

Q 5 = most of the matter in universe is made up of plasma.

Explanation:

Plasma:

" The ionized gaseous mixture consist of atoms, ions and electrons is called plasma"

The plasma was first time identified by William Crookes in 1879. More than 99% universe matter is consist of plasma.

It is the fourth state of matter, the other three are solid, gas and liquid. The most of matter in the universe is plasma. When heat is supplied to the atoms, they gain energy the electrons in atom thus escape from the atom by gaining the energy and create the positive charge. Thus ions are formed. When heat is constantly supplied, the ionization process continue to take place and produce large number of positive charges, free electrons but some atoms not get ionized and remain neutral. Thus a cloud of free electrons , positive charge and neutral atoms is formed which is called plasma.

Examples:

The shining stars, lightning bolts, fluorescent light, flames, electrical current which passes through neon gas are some examples of plasma.

the answer is c.the valence of the atoms combine .
