Special properties of water are its high heat capacity and heat of vaporization, its ability to dissolve polar molecules, its cohesive and adhesive properties, and its dissociation into ions that leads to generating pH. Understanding these characteristics of water helps to elucidate its importance in maintaining life.
Don't smoke, drive less, don't let toast burn, use an electrical fire instead of a wood one....
I can't think of anything else.
Answer:
Element
Explanation:
Each different kind of atom represents an atom. Elements like atoms are considered to be distinct substances that cannot be split into simpler substances. Such substances are known to be made up of just one kind of atom.
Like an atom, elements are made up of protons, neutrons and electrons. Both the protons and neutrons are found in the nucleus of the atom.
Answer:
i think its A
Explanation:
bc the nucleus is the very center of whatever the organism is.
Given :
Measurements
.
To Find :
The multiplication using significant figures .
Solution :
We know , the least number of significant figures in any number of the problem determines the number of significant figures in the answer.
So , significant figure( S.F) in 4.5 cm is 2 .
S.F in 2000.0 cm is 5 .
S.F in 4 cm is 1 .
So , minimum S.F is 1 .
Therefore , S.F of their product is 1 .
Now , multiplying them we will get :

Now , converting 36000 in 1 significant digit .
First we will write it in exponential 2 S.F form.

Now , to convert 3.6 into 1 S.F we should round off this .
So , round off 3.6 we will get 4 .
Therefore , The multiplication using significant figures is
.
Hence , this is the required solution .
