During melting the K.E of the particles decreases which i and During boiling K.E increases
Polarity is about PARTIAL charges. There is no real charge involved. For example water (H2O) is a polar molecule, because O has a stronger electronegativity than H (that means O attracts electrons stronger than H). Because of this attraction the electrons are often next to the O and so we can say that O has a negative partial charge and both H's has a positive <span>partial </span>charge.
Non polar means no partial charged.
I hope I could help a bit (and sorry for the bad english)
It’s likely Paleozoic because we are living in 2020 and 541 is the closet we can go to that
Answer:
covalent bonds
Explanation:
The covalent bonds between hydrogen and oxygen atoms in water are polar covalent bonds. The shared electrons spend more time near the oxygen nucleus, giving it a small negative charge, than they spend near the hydrogen nuclei, giving these molecules a small positive charge.
