Answer:
c) Young's modulus Toughness.
Explanation:
The charpy impact test is well known in the Engineering field specifically in stress, strain and mechanical of fracture.
A theoretical definition is that the test determines the amount of energy absorbed by a material during fracture.
Answer: The number of gram of ammonia gas (
) contained in the a 3.0L vessel at 305 K with a pressure of 1.50 atm is 3.048 g.
Explanation:
Given: Volume = 3.0 L
Temperature = 305 K
Pressure = 1.50 atm
Formula used to calculate the number of moles is as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
![PV = nRT\\1.50 atm \times 3.0 L = n \times 0.0821 L atm/mol K \times 305 K\\n = \frac{1.50 atm \times 3.0 L}{0.0821 L atm/mol K \times 305 K}\\= \frac{4.5}{25.0405}\\= 0.179 mol](https://tex.z-dn.net/?f=PV%20%3D%20nRT%5C%5C1.50%20atm%20%5Ctimes%203.0%20L%20%3D%20n%20%5Ctimes%200.0821%20L%20atm%2Fmol%20K%20%5Ctimes%20305%20K%5C%5Cn%20%3D%20%5Cfrac%7B1.50%20atm%20%5Ctimes%203.0%20L%7D%7B0.0821%20L%20atm%2Fmol%20K%20%5Ctimes%20305%20K%7D%5C%5C%3D%20%5Cfrac%7B4.5%7D%7B25.0405%7D%5C%5C%3D%200.179%20mol)
It is known that moles is the mass of substance divided by its molar mass.
Hence, mass of ammonia gas (molar mass = 17.03 g/mol) is as follows.
![Moles = \frac{mass}{molar mass}\\0.179 mol = \frac{mass}{17.03 g/mol}\\mass = 3.048 g](https://tex.z-dn.net/?f=Moles%20%3D%20%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D%5C%5C0.179%20mol%20%3D%20%5Cfrac%7Bmass%7D%7B17.03%20g%2Fmol%7D%5C%5Cmass%20%3D%203.048%20g)
Thus, we can conclude that the number of gram of ammonia gas (
) contained in the a 3.0L vessel at 305 K with a pressure of 1.50 atm is 3.048 g.
Answer:
the action or process of differentiating or distinguishing between two or more things or people.
Technician A is incorrect so that means Technician B is correct.
By increasing magnification you decrease the field of view.
The answer is A.
Hope this helps.
