Chemistry

Answer:

When an object is heated up, its particles gain more kinetic energy and hence its internal energy increases. A change in state will also result in a change in internal energy.

When an object cools down, heat is withdrawn from it. Hence, the entropy of the object decreases. But the decrease in entropy leads to the transfer of energy to the surrounding.

I hope this helps you! Good luck with school! :D

1 . a chemical bond formed by the electrostatic attraction between ions covalent bond
liberstina [14]

Explanation:

When there occurs sharing of electrons between two chemically combining atoms then it forms a covalent bond. Generally, a covalent bond is formed between two non-metals.

An ionic bond is defined as the bond formed due to transfer of one or more number of electrons from one atom to another. An ionic bond is always formed between a metal and a non-metal.

Every atom of an element will have orbitals in which electrons are found. These orbitals are known as energy level.

A molecule is defined as the smallest particle present in a substance or atom.

A metallic bond is formed due to mobile valence electrons shared by positive nuclei in a metallic crystal.

Thus, we can conclude that given statements are correctly matched as follows.

1).  a chemical bond formed by the electrostatic attraction between ions - ionic bond

2).  a chemical bond formed by two electrons that are shared between two atoms - covalent bond

3). the orbitals of an atom where electrons are found - energy level

4).  the smallest particle of a covalently bonded substance - molecule

5).  a bond characteristic of metals in which mobile valence electrons are shared among positive nuclei in the metallic crystal - metallic bond

Why is fossil fuel considered a nonrenewable energy source?​
IRINA_888 [86]

Answer:

\boxed {\tt Takes \ many \ years \ to \ replenish}

Explanation:

A nonrenewable is a resource that cannot quickly be regenerated. A nonrenewable resource will eventually run out, and it cannot be remade for many years.

For example, <u>fossil fuel </u>is formed from fossils after millions of years of heat and pressure turn them into fuel. Since they take many years to create, they are a <em>nonrenewable energy source.</em>
