A. Sound travels slower in air because of the huge distance between air particles

Explanation:

Sound is a mechanical wave that needs a tool for the propagation. There is no a medium, sound cannot walk through easily or readily. This means that sound cannot be propagated through a vacuum.

A vacuum is one empty space without any kind of particles in side. Sound waves travel fastest the many in solids because the particles are dense and also close come one another. The speed of sound in air is the least because of the huge distance in between air particles. Therefore, the speed of sound is tool dependent

Mixture: the components of a mixture can be be separate by physical approaches like filtration, decantation or magnetic separation etc

Compounds : the components cannot be separated by physical methods

1) the dirty water : we space able to different the solid from the dirty water yet water remains therefore so

Dirty water is a mixture of heavy particles and liquid. The is both a mixture and pure substance.

2) compound is pure substance comprised of two more more species of elements

so the correct answer will certainly be

D.Candace is incorrect. Substance A is a pure substances, because it is a compound. A link is comprised of 2 or more different elements. A mixture is comprised of different molecules no bonded together.

You are watching: Which factor has the greatest effect on the melting point of a crystalline solid

3) Mixture can be be separated by physical methods

pure substances cannot be be separated by physics means

mixture is consisted of of 2 or more substance

a pure substance is homogeneous

Answer from: HeroesofOlympus96951
rapid motion of hard particles mixed with water: mudflowslow movement of solid particles down a slope: creeprapid movement of solid particles down a slope: landsliderapid movement of hard particles blended with water: earthflow

Explanation:

An earthflow is intermediate to mudflow and also creep. The is the form of massive wasting that involves movement that solid corpuscle saturated with water, not necessarily mixed with large quantities that it.
