<span>A fast-flowing river of air that forms when two air masses of very different temperatures meet is called a jet stream :)</span>
(D)an atom can join with other kinds of atoms.
Basically he explained what a molecule is.
Density - Calculated from measurements of mass and volume
Atom - the basic particle of matter
Motion - calculated from measurements of distance and time
Energy - can change form and move matter
Can't see the last one but you know process of elimination soo
Answer:
covalent, which repel water molecules
they contain ions, which make the entire molecule hydrophilic
they are less dense than liquid water, so they float on the surface
most of their bonds are nonpolar covalent, so they are not attracted to water
Your answer
Explanation:
<h2>Answer:</h2>
The correct answer is the option C.
Which is we add equal amount of salt in all the water samples.
<h3>Explanation:</h3>
- As in experiment we have to indicate that the boiling point of water increases with the addition of salt.
- Now we also know that water contains many salts as compared to the distilled water.
- So the boiling points of simple water and distilled water would be bit different.
- So we cannot choose one for our experiment. Instead we use all water samples of equal volume adding equal amount of salt in all samples.
- Then we will compare results for a net answer/result of experiment.
