Answer: Covalent
Explanation:
A covalent compound is formed when an element shares its valence electron with another element. This compound is formed between two non metals. Example:
An ionic compound is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and the element which accepts the electrons is known as electronegative element or non metal. Example:
Explanation:
When water is heated up then its molecules move rapidly from one place to another. Hence, kinetic energy of the molecules tend to increase.
Also, K.E =
where, T = temperature
Therefore, more is the increase in temperature more will be the mean molecular speed change in the water molecules.
As a result, mean molecular speed change increases with increase in temperature and vice-versa.
