The temperature of water is cooler in deep oceans. The temperature there goes to 0°C to -3°C below which the water freezes. The water on the surface of the oceans and deep inside it varies because of the difference in energy of the two layers. One of the widest use of cold water is air conditioning. Cold water has a higher density than warm water. Water gets colder with profundity since chilly, salty sea water sinks to the base of the sea beds underneath the less dense hotter water close to the surface.
Answer: Rutherford.
Explanation:
It was the scientist Ernest Rutherford who, by 1911, performed the gold foil experiment in which α particles were shoot to a thin foild of gold.
That experiment showed that although most α particles passed through the thin gold foild, some of them were deviated in small angles and some other were bounced backward.
The conclusion of the experiment was that the atom contained a small dense positively charged nucleous and negative particles (electrons) surroundiing the nucleous. Being the space in between the nucleous and the electrons empty.
Before Rutherford's experiment the model of the atom was that of the plum pudding presented by J.J Thomson, in which the atom was a solid positively charged sphere with embeded negative charge uniformly distributed in it.

Answer:
![rate=k[A_2]](https://tex.z-dn.net/?f=rate%3Dk%5BA_2%5D)
Explanation:
Hello,
In this case, given the information on the table, we notice that in the first and second run we left the concentration of A constant whereas the concentration of B was doubled from 1.0M to 2.0M, even do, we notice that the concentration of B does not affect the rate as it remains constant in 4M/s.
Nevertheless, by doubling the concentration of A, we double the rate, that is from 1.0 M to 2.0 M, we are able to rise the rate from 4.0 M/s to 8.0 M/s, for that reason the rate law is zeroth-order with respect to B and first-order with respect to A, that in formula is:
Best regards.
