If the states of matter have changed such as from solid to liquid, you have to remove or add energy.

Answer: Option (A) is the correct answer.

Explanation:

It is known that kinetic energy is the energy obtained by an object due to its motion.

And, when we increase the temperature of a substance then there will occur an increase in the kinetic energy of its molecules.

Also, K.E = $\frac{3}{2}kT$

So, kinetic energy is directly proportional to the temperature. As a result, on increasing the temperature more number of collisions will take place between the molecules.

Therefore, we can conclude that amount of kinetic energy in the substance’s particles changes its states of matter.

What is another name for energy lost through heat and sound?

Arturiano [62]

Answer:Figure 1. Energy losses in an incandescent light bulb are very large; most of the input energy is lost in the form of heat energy. This means that when energy is converted to a different form, some of the input energy is turned into a highly disordered form of energy, like heat. ...

When two fluorine atoms bond together in F2, what type of covalent bond do they form?

Angelina_Jolie [31]

The correct statement is " A single bond, because they overlap orbitals to share one pair of electrons." A fluorine atom is unstable with 7 electrons in its valence shell and so needs one more electron to achieve stability. This is according to the octet rule which states that an atom will gain or lose electrons until there are 8 electrons in its valence shell. So each fluorine donates an electron to form a single pair and the $F_2$ achieves a noble gas configuration.
