Answer:

See the answer beloew, please.

Explanation:

The concepts of heat and temperature are related, but they are not the same. Temperature refers to a physical quantity which indicates the amount of heat. The latter corresponds to the energy that moves from one body to another, thus being able to raise or lower the temperature.

As they pass through the rock cycle, atoms:

Arlecino [84]

Answer:

Option (C)

Explanation:

Atoms are the basic structures that are combined to form minerals, which are further accumulated giving rise to the formation of rocks. These atoms plays a significant role in the formation of rock and their significant characteristics.

When atoms are passed through the rock cycle, they are not able to move at the same rate, but they can move at a different rate. When a rock changes from one kind to another, its constituent minerals and atoms also alters, forming a different rock type with variable characteristics and properties.

Thus, the correct answer is option (C).

You've just solved a problem and the answer is the mass of an electron, me=9.11×10−31kilograms. How would you enter this number

mihalych1998 [28]

The mass of an electron can be expressed in the box as $\boxed{{m_e} = 9.1 \times {{10}^{ - 31}}{\text{ kg}}}$ .

Further explanation:

Atom is the smallest particle that can be present in any element. It is also known as the building unit of matter. Each atom has a central part that is known as the atomic nucleus. There are three subatomic particles that constitute the atom. These particles are protons, neutrons, and electrons. The atomic nucleus consists of protons and neutrons, both are collectively called nucleons. Electrons revolve around the nucleus of an atom in definite orbits.

Protons are positively charged subatomic particles, electrons are negatively charged and neutrons have no charge. Since electrons carry a unit negative charge, these create an electric field around them. These also participate in nuclear reactions. The mass of an electron $\left( {{m_e}} \right)$ is $9.1 \times {10^{ - 31}}{\text{ kg}}$ , that of protons is $1.6726219 \times {10^{ - 27}}{\text{ kg}}$ and that of neutrons is $1.674927471 \times {10^{ - 27}}{\text{ kg}}$ . The electrons are responsible for chemical properties of elements. The distribution and arrangement of electrons is used to predict whether the element will be inert or reactive.

Therefore the required answer is $\boxed{{m_e} = 9.1 \times {{10}^{ - 31}}{\text{ kg}}}$ .
