Which of the following materials has the highest density?
A. O water vapor
B. O steam
C. O liquid water
D. O ice
Answer:
Answer is C. liquid water.
Explanation:
I hope it's helpful!
Liquid water has the highest density. Therefore, the correct option is option C among all the given options.
What is density?The density of a substance is defined just like its weight per unit volume. In other words, density is the mass-to-volume ratio or mass for every unit volume. It quantifies how much "stuff" a thing possesses in an unit volume (cubic meter or cubic centimeter).
Density is a measure of how closely stuff is packed together. The density principle was established by the Greek scholar Archimedes, which is simple to compute if one know the equation and its associated units. Lquid water has the highest density.
Therefore, the correct option is option C among all the given options.

How does salinity vary with freezing and melting?
Question 3 options:
Freezing increases salinity, while melting decreases salinity.
Both freezing and melting decrease salinity.
Freezing decreases salinity, while melting increases salinity.
Both freezing and melting increase salinity.
Answer:
For every 5 psu increase in salinity, the freezing point decreases by 0.28 degrees Celsius (0.5 degrees Fahrenheit); thus, in polar regions with an ocean salinity of about 32 psu, the water begins to freeze at -1.8 degrees Celsius (28.8 degrees Fahrenheit).
Explanation:
Freezing increases salinity, while melting decreases salinity.

1. If a cell has waste it needs to store, it will store it:
A process that releases heat, such as freezing or condensation is called?
Answer:
exothermic
Explanation:
An exothermic reaction gives off heat energy. Condensation is the process by which water vapor turns into liquid water. This typically occurs when water vapor molecules come into contact with cooler molecules. This causes the water vapor molecules to lose some energy as heat which is a exothermic reaction.
When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction.

Explanation:
What is the overall reaction equation
Answer:
If m or n is zero, the reaction is zero order in A or B, respectively, and the rate of the reaction is not affected by the concentration of that reactant. The overall reaction order is the sum of the orders with respect to each reactant. If m = 1 and n = 1, the overall order of the reaction is second order
(m + n = 1 + 1 = 2).
Explanation:
what are ions and how do they work please send me answer
Answer:
hope it helps
please mark me brainliest
Explanation:
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
Explain why atoms increase in size when the atom gains electrons.

I'm flying too close to the sun
And I burst into fla-fla-flames
You make me glow
But I cover up, won't let it show

how many significant figures are needed in the answer when 1.31m is multiplied by 6.5 m
Answer:
two
Explanation:
The number of significant figures needed in the answer is 2.
This is because when finding the products of two numbers, the result is as accurate as the least number of significant figures of the numbers being multiplied.
Here the numbers being multiplied are;
1.31m
6.5m
1.31m has 3 significant figures
6.5m has 2 significant figures.
So, the product will have 2 significant figures

Find the mass of 1.25 moles Ca(OH)2.
According to the mole concept, the mass of 1.25 moles Ca(OH)₂ is 92.61 grams.
What is a mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.Mass=number of moles×molar mass=1.25×74.09=92.61 g.
Thus,the mass of 1.25 moles Ca(OH)₂ is 92.61 grams.
