Pwaves travel through a. solids b. liquids c. solids, liquids and gases d. solids and liquids

The correct answer is option C.

Explanation:

The P waves are the longitudinal earth quake waves which travels through the interior of the the earth. One of the type of seismic wave which travels fastest then other types of seismic waves.

The letter 'P' in P wave stand for pressure wave(formed of compressions and rarefactions) or primary wave (as it has highest velocity than other waves).

These waves can be transmitted through solids, liquids and gases.

Hence, the correct answer is option C.

The correct answer is D solids and liquids

The fastest waves created by an earthquake are P-waves . These waves travel through the Earth's interior structure and can pass through both solid and molten rock. They shake the ground back and forth but do little damage as they only move buildings up and down. P-wave is one of the two major types of seismic waves in seismology, where the other type is called S waves.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

i think it's c. i'm not sure but i think so.
