I know what you are wondering and the answer is simply crystals are more dense than water , so they sink but if you warm it up they can combine with it to become one.
dose this help?
Answer:
Newton's First Law of Motion
Explanation:
Without external forces acting on an object, the object tends to move at constant speed in a straight line. This property is referred to as inertia. Newton's first law states this natural observation.
The comet which is violent and large scale, causing sudden and violent upheaval is known as "Cataclysmic Comet"
Hope this helps!
Given that:
Distance , s = 18.5 m
Velocity , v = 3.85 m/s
Time , t =?
Since,
Velocity = distance/time
or
Time= distance/velocity
time= 18.5/ 3.85
time= 4.8 s
So the time elapse between the release of the ball and the ball passing home plate is 4.8 seconds.
Answer:
7.9
Explanation:
When we put the metal piece in the liquid (which is in the graduated cylinder), how much it goes up is equal to the volume of the piece we inserted.
So now we know that the volume of that piece of unknown metal is 7mL (which is the same as 7
).
Density is 
.
So the density of that piece of metal is 
Which leaves us with a final density of 7.9
