Do you need to know from solid to liquid,liquid to gas or gas to liquid?
Answer:
Smell: Most chemists can identify solvents by their distinctive smells (though this is a pretty bad idea). ¹
Melting point: If you've got very pure crystals, you can use their melting point to figure out which of several possible chemicals you've got.

I hope this helps and pls mark me brainliest :)
<span> An object with a high specific heat would change temperature more slowly than one with low specific heat. Water, for example has a very high specific heat so it requires a lot of energy to heat it up. It also takes a while for water to cool down because it holds that heat for a long time. <3</span>
Here is your answer
Ru(MnO4)2
We know that
valency of Ru=2
Valency of permanganate(MnO4)= 1
So, on combining the two
Ru(MnO4)2 is obtained by transferring of electrons.

Answer : The correct option is (A) Hydrogen region of the molecule.
Explanation :
As we know that the water molecule has two hydrogen atom and one oxygen atom. The hydrogen atom has partial positive charge and oxygen has partial negative charge.
In the charged plate, the negative attracts positive and positive attracts negative. So, the hydrogen atom attracted to the negative plate and the oxygen atom attracted to the positive plate.
When water molecule placed between oppositely charged metal plates which is positively charged, then the hydrogen atom which is positively charged attracted towards the negative plate.
