Answer: Adiabatic process is a process in which heat is constant
Explanation:
The processes in which temperature remains constant is called isothermal process.
The process in which Volume remains constant is called isochoric process.
The process in which pressure remains constant is called isobaric process.
The process in which no heat is gained or lost by the system, Hence heat remains constant is called as adiabatic process.
Thus option d) heat is correct

the element chlorine is a gas. it's formula is cl2 . how many different masses of the cl2 molecule would you expect to find in a sample of chlorine gas ? explain your answer
Answer:
the answer is 3.33⋅1023 molecules of Cl2. Note that 6.022⋅1023 is also known as Avogadro's number, and it can be referred to as the number of molecules in one mole of that substance. Also, I calculated 70.9 because 35.45 g/mol (the mass of one Chlorine atom) times 2 is 70.9 g/mol (Cl2 has two Chlorine atoms).

Which of the following has the LONGEST wavelength
A.) a lion growling at a frequency of 85 Hz
B.) a bass guitar playing a note at a frequency of 150 Hz
C.) a man speaking at a frequency of 520 Hz
D.) an opera singer singing at a frequency of 2100 Hz
Answer:
D.) an opera singer singing at a frequency of 2100 Hz
Explanation:
Wavelength is inversely proportional to frequency.
The one having the LONGEST wavelength is a lion growling at a frequency of 85 Hz and the correct option is option A.
What is Electromagnetic scale?The electromagnetic spectrum is a range of frequencies corresponding to wavelengths which are a few kilometres to a fraction of the size of an atomic nucleus in the spectrum of electromagnetic waves.
As a wave, light has several basic properties that describe it. One is frequency, which counts the number of waves that pass by a given point in one second.
Another is wavelength, the distance from the peak of one wave to the peak of the next. These properties are closely and inversely related: The larger the frequency, the smaller the wavelength — and vice versa.
A third is energy, which is similar to frequency in that the higher the frequency of the light wave, the more energy it carries.
Therefore, The one having the LONGEST wavelength is a lion growling at a frequency of 85 Hz and the correct option is option A.

(40) The difference of squares of two numbers is 180. The square of the smaller number is 8 times the larger number. Find
the two numbers.
The difference of squares of two numbers is 180. The square of the smaller number is 8 times the larger number. Find the two numbers.
Solution:-Let the larger number be x
And, the square of the smaller number be 8x
ATQ ,x² − 8x = 180
⇒ x² − 8x − 180 = 0
⇒ x² − (18 − 10)x − 180 = 0
⇒ x² − 18x + 10x − 180 = 0
⇒ x (x − 18) + 10(x − 18) = 0
⇒ (x − 18) (x + 10) = 0
⇒ x − 18 = 0, x + 10 = 0
⇒ x = 18, x = −10
⇒ x = −10, 18
[tex] \therefore [/tex] Either, x = −10 and x = 18
x = 18 (Positive value)
Now, the square of the smaller number = 8x = 8 × 18 = 144
So, the square of the smaller number = [tex]\sqrt{144} [/tex] = 12
The two numbers are 18 and 12. [Answer]Balance the following chemical equation by providing the correct coefficients:

2 Na + Cl2 --> 2 NaCl
What is the mole ratio of sodium to sodium chloride?
Answer: The mole ratio of sodium to sodium chloride 2:2.
Explanation:
As the given reaction equation is as follows.
[tex]2Na + Cl_{2} \rightarrow 2NaCl[/tex]
Here, 2 moles of sodium reacts with 1 mole of [tex]Cl_{2}[/tex] and leads to the formation of 2 moles of NaCl.
This means that 2 moles of sodium gives 2 moles of NaCl on reaction with chlorine.
Hence, the ratio of moles of sodium to sodium chloride is 2:2.
Thus, we can conclude that the mole ratio of sodium to sodium chloride 2:2.

An ideal gas is held in a rigid container at temperature of 201∘C. Upon cooling the gas, the pressure decreases by a factor of 2.0, while the volume and the amount of gas remain constant. What must be the final temperature of the gas?
Answer:
237 K
Explanation:
Given that,
Initial temperature, T₁ = 201⁰C = 474 K
Let P be the initial pressure. Upon cooling the gas, the pressure decreases by a factor of 2.0, while the volume and the amount of gas remain constant.
Final pressure = P/2
The relation between the pressure and temperature is as follows :
[tex]\dfrac{P_1}{P_2}=\dfrac{T_1}{T_2}[/tex]
Put all the known values,
[tex]\dfrac{P}{\dfrac{P}{2}}=\dfrac{474}{T_2}\\\\2=\dfrac{474}{T_2}\\\\T_2=\dfrac{474}{2}\\\\T_2=237\ K[/tex]
So, the final temperature of the gas is equal to 237 K.

The brightness of a light correlates to its amplitude. The higher the amplitude, the brighter the light will appear. Which of the waves below depicts the brightest light?
Answer:
Wave X is the brightest light
Explanation:
The amplitude of a wave refers to the maximum upward or downward displacement of a wave from its rest position. This implies that the amplitude is the measured distance from rest position to crest position. Similarly, the amplitude is also measured from the rest position to the trough position.
The crest of a wave is the point on a travelling wave that has the maximum amount of positive or upward displacement from the rest position. The trough of a wave is the point on the travelling wave that has the maximum amount of negative or downward displacement from the rest position.
From the wave diagrams shown in the attachment below, the wave that shows the highest amount of upward or downward displacement from the rest position (x - axis) is wave X. Since the brightness of a light wave increases with increaese in amplitude, wave X will have the highest amount of brightness.

How many moles of HCl can be neutralized by 0.1 liter of 0.5 M NaOH? A. 0.1 B. 0.05 C. 0.5 D. 0.4
Answer:
B. 0.05
Explanation:
The reaction that takes place is:
HCl + NaOH → NaCl + H₂OAs 1 mol of NaOH reacts with 1 mol of HCl, to solve this problem what we need to do is calculate the number of NaOH moles contained in 0.1 liters of a 0.5 M solution:
Molarity = Moles / litersMoles = Molarity * liters0.5 M * 0.1 L = 0.05 molThe moles of Hydrogen chloride required to neutralize the 0.1 liter of 0.5 M Sodium hydroxide is 0.05 moles.
How do we calculate moles?Moles (n) of any substance will be calculated by using the molarity (M) as:
M = n/V, where
V = volume
Given chemical reaction is:
NaOH +HCl → NaCl + H₂O
Moles of 0.5M NaOH will be calculated as:
n = (0.5)(0.1) = 0.05 moles
From the stoichiometry of the reaction it is clear that:
1 mole of NaOH = react with 1 mole of HCl
0.05 mole of NaOH = react with 0.05 mole of HCl
Hence option (B) is correct.
