An electromagnet acquires magnetism through electricity.
A bar magnet comes with magnetism already stored within it and doesn't need to rely on on another object for power.
Shawty's like a melody in my head

Replay
Remember the first time we met
You was at the mall wit yo friend
I was scared to approach ya
But then you came closer
Hopin' you would give me a chance
Who would have ever knew
That we would ever be more than friends
We're real worldwide, breakin' all the rules
She like a song played again and again
That girl, like something off a poster
That girl, is a dime they say
That girl, is a gun to my holster
She's running through my mind all day, ay
Shawty's like a melody in my head
That I can't keep out, got me singin' like

See you been all around the globe
Not once did you leave my mind
We talk on the phone, from night 'til the morn'
Girl, you really changed my life
Doin' things I never do
I'm in the kitchen cookin' things she likes
We're real worldwide, breakin' all the rules
Someday I wanna make you my wife
That girl, like something off a poster
That girl, is a dime they say (Hey)
That girl, is a gun to my holster
She's running through my mind all day, ay

I can be your melody
Oh, girl, I could write you a symphony
The one that could fill your fantasies
So come baby girl let's sing with me, ay

Answer:
The volume of a gas approaches zero as the temperature approaches absolute zero.
Step-by-step explanation:
You may have done a <em>Charles' Law experiment</em> in the lab, in which you measured the volumes of a gas at various temperatures.
You plotted them on a graph, and perhaps you were asked to extrapolate the graph to lower temperatures.
Your graph probably looked something like the one below.
There is clearly an x-intercept at some low temperature.
Inference: The volume of a gas approaches zero as the temperature approaches absolute zero.
Answer:The IUPAC name of compound would be Hex-3-yn-ol
Explanation:
When butyne is treated with LDA it leads to generation of carbanion on the terminal alkyne.
As LDA is disopropyl amide which happens to be quite a good base and hence it is sufficiently basic to abstract the acidic proton on the terminal alkyne.
So this proton abstraction leads to generation of a carbanion which can now acts as a nucleophile in step 2.
In step 2 the generated carbanion attacks the strained epoxide ring to open the strained epoxide ring .The product of step 2 leads to generation of hex-3-yn-1-olate
Further on treating the product formed in step 2 with the dilute acid it leads to the formation of alcohol as the negative charge on oxygen can now be neutralised.
Kindly refer the mechanism for structure of compounds.
Density of unit cell is mathematically expressed as
D =
where, Z = number of atoms/unit cell = 4 (For FCC structure)
Atomic weight of Cu = 63.5 g
a = edge length = 351 pm = 351 X 10^-10 cm
Avagadro's number = 6.023 X 10^23
∴ Density of unit cell =
= 9.752 g/cm3
Now, for FCC structure a = √8 r
where r = radius of Cu
∴ r = a/√8 = (351 X 10^-10)/√8 = 1.24 X 10^-8 cm = 124 pm
