The nickel, itself ferromagnetic, reduces the magnetism in stainless steel but not to zero. Austenitic stainless steel is defined as the steel crystal structure that is face centered cubic which is the same structure hot iron has as one of the allotropes of iron. Nickel above a certain percentage (18) stabilizes austenite structure just as if you took carbon steel and heated it above 730–770 C. Above this temperature the structure is FCC and above the Currie temperature where magnetism is killed due to the isotopic symmetry of the structure. However, you can still get a small magnetic attraction from austenitic stainless steel if it is cold worked, heat treated a certain way or welded. So it is not a guarantee that austenitic stainless is totally non magnetic.
Answer:
9. Electron Affinity
10. The second option....
<span> As we know that MgI2 (magnesium iodide) when dissociated it gives more ions than the KI so it has more boiling point as its boiling point is high it means that it boils more so it has low vapor pressure and freezing point
On the other hand as we know that KI dissociates into two ions so so it has high freezing and vapor pressure
hope it helps</span>
Answer:
A
Explanation:
B - Can't be - Ionic bonds are formed by oppositely charged ions
C - Can't be - This is a covalent bond
D - Can't be - This is an induced dipole or a van Der waals attraction
E - This is a permanent dipole dipole attraction
Answer:
The electric force is conservative.
Since
ΔK = −ΔU,
Kf − Ki =Ui −Uf.
We have,
Kf = 0
Ui = 0.
Thus Ki =Uf.
<u>so ,at 10 fm Uf = (2×10)−12 J.</u>
