<span>Kinetic energy is the energy at move or at motion. The kinetic energy of objects depend on its mass (m) and its </span>velocity (v)<span>. The mass of an object can be measured in kilograms while its mass can be measured in meters per second. The objects' energy at motion is very dependent to its mass and velocity therefore, the formula in finding the kinetic energy of an object is </span>

K = 1/2 x mass (m) x velocity (m/s)2

<span>On the other hand, the kinetic energy of atoms and molecules are measured differently. It is measured through temperature.<span>

A molecule that forms when atoms of the same element bond together is called a(n)________
Mice21 [21]

Answer: element.


Justification:


1) A molecule is the union of two or more atoms.


2) When two or more atoms of different elements bond together, the molecule formed is a compound.


For example: one atoms of hydrogen and one atom of chlorine form the molecule HCl, which is a compound (hydrogen chloride).


3) When the molecules is formed by two atoms of the same element, it is not called a compound, but element. Some examples of this are the diatomic gases:


H₂: hydrogen


Cl₂: chlorine


Br₂: bromine


O₂: oxygen


S₂: sulfur


N₂: nitrogen.

Represente lo que ocurre mediante flechas cuando dos cargas negativas, dos cargas positivas y una carga positiva y otra negativa
pochemuha

Answer:

Neutral.

Explicación:

Cuando dos cargas negativas, dos cargas positivas y una carga positiva y una carga negativa se unen, los átomos se vuelven neutrales porque las cargas opuestas cancelan el efecto de la otra. Si hay igual número de cargas y además son opuestas entre sí, entonces todas estas cargas cancelan el efecto de la otra formando el átomo neutral, pero si hay diferencia en el número de cargas, entonces la carga que es alta en número aparece en el átomos.

A heat energy of 645 J is applied to a sample of glass with a mass of 28.4 g. Its temperature increases from –11.6 ∞C to 15.5 ∞C
Anika [276]
The heat that is required to raise the temperature of an object is calculated through the equation,
                        heat = mass x specific heat x (T2 - T1)
Specific heat is therefore calculated through the equation below,
                                specific heat = heat / (mass x (T2 - T1))
Substituting,
                                specific heat = 645 J / ((28.4 g)(15.5 - - 11.6))
The value of specific heat from above equation is 0.838 J/g°C.

The answer to the question?
Artemon [7]

Answer:

atomic particles

The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
