The boiling point of Sodium chloride(aq) is higher and the freezing point of Sodium chloride(aq) is lower.
The boiling point is the temperature at which the pressure exerted by the surroundings upon a liquid is equal to the pressure exerted by the vapour of the liquid.
Usually, in this context, you would be referring to the boiling and freezing point of a Sodium chloride solution compared to pure H2O.
The boiling point of pure water is 100 degrees Celcius (212 Fahrenheit), and the freezing/melting point is below 0 degrees Celcius (32 Fahrenheit). For a solution, the boiling point is raised and the melting point is lowered.
This means that water will stay liquid for an increased range of temperature. Depending on the amount of Sodium chloride solute in the water, the boiling and melting points may change a few degrees.

states that volume occupied by a fixed quantity of a gas is directly proportional to the absolute temperature (Kelvin) at constant pressure.
Further Explanation:
Charles’s law:
Charles’s work showed that at constant pressure, the volume-temperature relationship for a fixed amount of gas is linear. In other words, Charles’s law can be stated that at constant pressure, the volume occupied by a fixed amount of a gas is directly proportional to its absolute temperature (Kelvin). This relationship is known as Charles’s law.
The mathematical representation of Charles’s law is,
[P and n are constant]
Where,
The relationship can also be expressed as,
[P and n are constant]
Or,
[P and n are constant]
Results of Charles’s law are as follows:
The volume (L) versus temperature (T) curve of Charles’s law is represented in the attached diagram.

Charles's Law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions
There are several gas equations in various processes:
PV = nRT
PV = NkT
N = number of gas particles
n = number of moles
R = gas constant (8,31.10 ^ 3 J / kmole K
k = Boltzmann constant (1,38.10 ^ -23)
n = = N / No
n = m / M
n = mole
No = Avogadro number (6.02.10 ^ 23)
m = mass
M = relative molecular mass
In the same temperature and pressure, in the same volume conditions, the gas contains the same number of molecules
So it applies: the ratio of gas volume will be equal to the ratio of gas moles
V1: V2 = n1: n2
2. Boyle's Law
At a fixed temperature, the gas volume is inversely proportional to the pressure applied
p1.V1 = p2.V2
When the gas pressure is kept constant, the gas volume is proportional to the temperature
V1 / T1 = V2 / T2
When the gas is heated in a tube whose volume does not change, the gas pressure in the tube is proportional to its absolute temperature
P1 / T1 = P2 / T2
Combined with Boyle's law and Gay Lussac's law
P1.V1 / T1 = P2.V2 / T2
P1 = initial gas pressure (N / m2 or Pa)
V1 = initial gas volume (m3)
P2 = gas end pressure
V2 = the final volume of gas
T1 = initial gas temperature (K)
T2 = gas end temperature
So the correct answer is Charles' Law, where at constant pressure, the volume of gas will be inversely proportional to its temperature

Answer:
The ionic compound NaCl has a Face Centered Cubic unit cell
The site for atoms are Face, center and Edges corner.
Effective number of atoms
Na+
1centers + 12edges x = 4 Na+
Cl-
6face x + x8 corners = 4Cl-
This is just one unit cell effective atom, there are thousand's of such unit cells are combined to form one such structure of NaCl. The real formula of NaCl is Na4Cl4 but for simplicity we use empirical formula that is NaCl.
B) radon
C) carbon monoxide
D) sulfuric acid
A secondary pollutant is one that is not directly emitted but rather forms when primary pollutants react in the atmosphere. Among the options provided, sulfuric acid is a secondary pollutant. Correct option is D.
In the context of environmental science, a secondary pollutant is a type of pollutant that is not directly emitted. Instead, secondary pollutants are formed when primary pollutants undergo chemical reactions in the atmosphere. Among the options provided, option D) sulfuric acid is a secondary pollutant. The others - sulfur dioxide, radon and carbon monoxide - are primary pollutants, as they're emitted in this form from a source.
