D. Electronegativity and first ionization energy both increase as you
move up the periodic table.
Answer:
Explanation:
Solids are matters whose shape are usually fixed. They have a definite volume which be measured at any point. The particles of solids are usually arranged in an order manner or pattern based on their crystal lattices. Solid particles are tightly and closely packed together and are held by a very strong attractive force.
Liquids do not have a fixed shape. Liquids have a definite volume which can easily be determined. The particles of liquids are closely packed and held by a stronger attractive force than those of gases but less strong when compared solids.
Gases do not have a fixed volume or shape. They occupy any volume of space they are found in. Particle of gases are poorly packed and they are held by weak attraction forces between their particles.

So what’s the question? I’m confused
Answer:
See explanation
Explanation:
a) Every substance melts at a particular temperature known as the melting point of the substance. The melting point of ice is 0°C. Hence ice melts at 0°C.
b) There are three states of matter; solid liquid and gas. The particles of matter in each stage of matter possess varying degrees of freedom.
In the solid state, the intermolecular forces between the particles of water that compose ice are very strong. Hence the particles do not translate, they only vibrate or rotate about their mean positions.
In the liquid state, the magnitude of intermolecular interaction is less than that of the solids hence the molecules can translate but not with a high kinetic energy.
In the gaseous state, there is a minimum intermolecular interaction between particles theoretically hence the particles are really free to move about with a very high kinetic energy.
