Aqua Auras belong to the Quartz family. It's a synthetic type of Quarts that was enhanced with the help of gold coating, and sometimes other materials. The reason why it's called as aqua is because of its distinctive blue color thanks to the procedure which made it.
Answer: C
Explanation:
According to Neils Bohr, atoms contain electrons which are arranged in energy levels. The energy levels proceed from the lowest to the highest. When energy is supplied to an atom,it moves from lower to higher energy levels. The higher energy level is known as the excited state. Excited states are short lived and atoms quickly return to ground state with emission of the absorbed energy in the form of visible light. This visible light must have one of the seven colours observed in the visible spectrum; Red, orange, yellow, indigo, blue, green, violet. Energy required for this excitation is supplied by heating the substance in a flame.
Answer:
Explanation:
In a chemical change through chemical reactions, a new kind of matter forms. When a paint is mixed together, a physical change has occurred and not a chemical change. The different color one perceives is just a mere overlap between the reflected white and red color which produces another hue.
Not all color changes infers a chemical reaction. A paint is a complex mixture on its own.
In this case a double displacement reaction will take place.
Molecular Motion<span> is the speed at which molecules or atoms move dependent on temperature and state of matter.
Explanation:
</span>All molecules are<span> in constant motion. Molecules of a liquid have </span>a lot of<span> freedom of movement than those </span>in an exceedingly<span> solid. Molecules </span>in an exceedingly<span> gas have </span>the best<span> degree of motion.</span>
<span>
Heat, temperature </span>and also the<span> motion of molecules </span>area unit<span> all </span>connected<span>. Temperature </span>could be a life<span> of </span>the common K.E.<span> of the molecules </span>in an exceedingly<span> material. Heat </span>is that the<span> energy transferred between materials that have </span>completely different temperatures<span>. Increasing the temperature </span>will increase<span> the </span>travel<span> motion of molecules Energy </span>is expounded<span> to temperature by the relationship.</span>
