Liquid crystal molecules have very unique structures, allowing them to be highly affected by electric fields, changing their orientation in the liquid crystal structure. This is why they are used in LCD screens. They are also highly sensitive to changes in temperature. Therefore the answer is C.
Hope this helps!
Answer:
ionize
Explanation:
Acids are chemical substances that lose/donate their hydrogen ion (H+) when they react with water. This property of acids is termed IONIZATION. In a chemical reaction involving acids and bases, acids release their proton or hydrogen ion (H+) in the presence of water solutions to form a conjugate base, which is usually an anion.
For example, in the chemical reaction;
HX + H20 -------> X- + H30+
HX is the acid because it loses its electron to water and forms the anion, X-, which is the conjugate base. Hence, it can be said that acid HX ionizes in water.
Answer:
Densities of the solids and the liquids are expressed in units of grams per cubic centimeter (g/cm³) or in grams per milliliter (g/mL).
Densities of the gases are usually expressed in the units of grams per liter (g/L).
Explanation:
Density of a substance can be defined as the ratio of its mass and its volume.
The constituting atoms in the solids and liquids are fairly packed closely together.
<u>In general, a 1 cm³ or 1 mL volume of most of the solids and the liquids has mass of several grams.</u> Thus, densities of the solids and the liquids are expressed in units of grams per cubic centimeter (g/cm³) or in grams per milliliter (g/mL).
The constituent atoms or the molecules in the gases are far apart from each other when compared to the solids and the liquids.
<u>Thus, gases are much less dense and even about 1 L of gas have mass in range close to 1 gram.</u> Thus, densities of the gases are usually expressed in the units of grams per liter (g/L).
<u>Also, the density of the gases also depend upon the pressure and the temperature but these factors much not influence the density of the solids and the gases.</u>
