What is the speed of voice per minute?
In common everyday speech, speed of sound refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance. Sound travels faster in liquids and non-porous solids than it does in air. It travels about 4.3 times faster in water (1,484 m/s), and nearly 15 times as fast in iron (5,120 m/s), than in air at 20 degrees Celsius.
Why is density a characteristic of a substance and volume and mass are not?
The volume and mass of a substance are independent of the substance itself, but depend upon how much there is of the substance The density of a substance is the relation between how much volume you have of a substance and how much mass that volume has (and vice-versa). It is independent of how much there is of the substance and is thus a characteristic of the substance.

How does heating acid make metal dissovle faster?
Heating a substance causes the molecules within it to move more quickly. So imagine that every surface atom of the metal reacted with acid: the faster the reacted material can move away from the unreacted metal, the faster new acid molecules can get close enough to the metal to react.
How fast do solid dissovle in water?
The rate at which solids dissolve in water depends on factors such as temperature, surface area of the solid, agitation, and the solubility of the substance. Generally, smaller particles dissolve faster due to increased surface area for interaction with the solvent.
Will not dissovle?
"insoluble"
Do the particles of a substance move faster or slower as the substance?
