Answer:
Angle ABE measures 27°.
Explanation:
Refer to the attached diagram related to this question.
The given values are ∠ABE=2n+7 and ∠EBF=4n-13.
Clearly seen in the diagram, ∠ABE and ∠EBF are equal in measure.
Move variable components to one side of the equation.
Split both sides by 2.
The solution for n arrives at 10.
The next step is to calculate ∠ABE.
Consequently, the measurement of angle ABE is 27°.
The mass is 150,000 grams. Multiply 100 by 50 by 30 to determine the container's volume, which equals 150,000 cm^3. Since a milliliter is equivalent to one cubic centimeter, and given that the density of water is one gram per milliliter, it follows that the mass of water is 150,000 grams.
Moving on to the second issue
Let's tackle the second question first. Once you grasp that, the first question will be simpler. By the way, this is an excellent question to clarify. The concepts of less than and more than can be quite tricky in the sciences. Every question you encounter that utilizes less or more should be approached with caution.
As altitude increases, air pressure decreases (essential term: less highlight this sentence in color. Take a moment to reflect on it.)
As the pressure declines, less energy (again, key term) is required for water molecules to escape the surface. Thus, the boiling temperature is lower than it would be at sea level.
Answer to problem two: Lower
Problem One
Water reaches its boiling point when the greatest number of molecules can leave the water's surface. Equal to is the right answer. Although pinpointing the exact answer can be challenging, equal to is indeed the correct response.
The atomic number of the element indicated by the model is 8, corresponding to option 'C' in the question.
Response:
The conclusion to your inquiry is Pressure 1 = 1.73 atm
Clarification:
Data provided
Volume 1 = 5 l
Pressure 1 =?
Volume 2 = 12 l
Pressure 2 = 0.72 atm
Procedure
To resolve this issue, Boyle's law is applied
Pressure 1 x Volume 1 = Pressure 2 x Volume 2
-Finding Pressure 1
Pressure 1 = Pressure 2 x Volume 2 / Volume 1
-Replace values
Pressure 1 = 0.72 x 12 / 5
-Calculating
Pressure 1 = 8.64/5
-Final outcome
Pressure 1 = 1.73 atm
