OK so basically many experiments were done and Ernest Rutherford found that atoms had a positive charge and it contains most of its mass. and for the electron J.J. Thomson found that atoms have a negative charge after a various amount of study and experimentation
In my opinion the answer is D
There are different ways, but the most common is through water.Hope this helps.
<span>Dark matter has been given this name because it doesn’t seem to interact with regular matter in any way. It doesn’t collide with it, or absorb energy from it. We can’t see it or detect it with any of our instruments. We only know it’s there because we can see the effect of its gravity.</span>
Answer: Solid, Liquids, Plasma. Gas.
Explanation:
It retains its shape regardless of the shape of the container----- Solid
Particles move freely but do not separate from neighboring particles---- Liquids
This state, in which the particles are at extremely high temperatures, is rarely found on Earth---- Plasma
It expands to fill the volume of the container.------- Gas
There are four states of matter, of which the common ones are
Gases- whose particles are compressible and takes the shape and volume of its container
, Liquids - whose particles freely slide over each other and assumes the shape of the part of the container which they occupy and
Solids whose particles are rigid and maintain thier fixed volume and shape regardless of the container they are put .
The last one is the Plasma, a rare state of matter not common to earth nwhose particles are so hot that they exist around the sun, stars and outer space.
