What type of state is glass? please explain about it.

2 answers:

8 0

On a small time scale, glass is in a solid state. When you look at a window, it appears solid.

However, it has been observed that over a very long period, glass starts to act like a liquid.

It can thus be characterized by two different states depending on the time scale considered.<span />

I think the other answer is incorrect. Glass being a liquid is a misconception, from when glassmaking was imperfect and windows were thicker at the bottom of the pane than the middle. But that was from when the glass was MADE, after being heated and put into a liquid form.

- Standard state refers to

yulyashka [42]

Answer: The standard state refers to 1 atm and $25^{o}C$ .

Explanation:

It is known that a chemical/substance can either be present in a solid, liquid or gaseous state.

So, when the phase of a substance like solid, liquid or gas is present at 1 atmosphere pressure and at a temperature of $25^{o}C$ then it known as standard state of substance.

Thus, we can conclude that standard state refers to 1 atm and $25^{o}C$ .

If you dispense 40 ml of hexane, but it turns out you only need 5 ml, what should you do with the remainder?

Natasha2012 [34]

After subtracting the volume needed from the volume dispensed, we got a remainder of 35ml

<h3>Subtraction of Numbers</h3>

Given Data

Volume of Hexane dispensed = 40ml

Volume needed = 5 ml

Let us compute the amount of excess hexane/ the volume that will remain

Remainder = The difference in volume dispensed and the volume needed

Remainder = 40-5

Remainder = 35 ml

The remainder is 35ml
