Answer:
Background
Solids – relatively rigid, definite volume and shape. In a solid, the atoms and molecules are attached to each other. ...
Liquids – definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded. ...
Gases – no definite volume or shape
Answer:
A wave with small amplitude.
Explanation:
Amplitude us inversely proportional to energy so the smaller the amplitude, the higher the energy.
Hope it helps.
Answer:
C) Ionic bonds
Explanation:
The ionic bonds are the strongest bond, it occurs when a metal donates electrons and a nonmetal gain these electrons. They'll be together by electrostatic force.
Metallic bonds it the second strongest bond, it occurs between metals, which loses electrons. It's an electrostatic force, but weaker than the ionic compound because it occurs between the cation and the electron.
Covalent bonds are the weakest bond. It happens between metals and nonmetals, or nonmetals and hydrogen or between atoms of hydrogen. The force that joins the atoms depends on the polarity of the molecule. Polar molecules have dipole forces, nonpolar molecules, induced dipole forces. Also, hydrogen makes special dipole forces with nitrogen, oxygen, and fluorine, called hydrogen bond.
As the stronger is the force, as difficult it will be to break it. So, ionic bonds will demand more energy to become gas, and have high melting points.
Hi,
The answer should be C.
