how can fossil records be useful to determine the relative ages of rock layers and other fossils?

Answers

Answer:

If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time. Thus, the principle of faunal succession makes it possible to determine the relative age of unknown fossils and correlate fossil sites across large discontinuous areas.

what will happen to the atoms or sbstance when it freezes
​

Answers

Explanation:

Freezing is the process that causes a substance to change from a liquid to a solid. Freezing occurs when the molecules of a liquid slow down enough that their attractions cause them to arrange themselves into fixed positions as a solid.

When freezing a substance if the substance has successfully frozen , then the atoms in the substance won’t change in mass or have any chemical reactions since freezing is a physical change and the ratio of mass of atoms are in a fixed ratio . Nothing actually happens to the atoms I think .

Describe what happens to the arrangement and movement of particles when a substance boils.

Answers

Answer:

When boiling a substance, the particles obtain more kinetic and potential energy from the heat being delivered. The kinetic energy means that the particles starts moving more intensely, and the potential energy means that the particles start to move away further from each other, which means the substance expands in volume.

Explanation:

When a liquid is heated, the particles gain energy and begin to move faster and faster, expanding the liquid. As the liquid warms, the most energetic particles at the surface escape as vapor from the surface.

What are particles?

A particle is a small localized object to which several physical or chemical properties, such as volume, density, or mass, can be assigned in the physical sciences.

Atoms are small units of matter that contain a number of particles known as subatomic particles. The term particle, on the other hand, refers to any small object.

As a result, the primary distinction between atoms and particles is that atoms are small units composed of multiple particles, whereas particles are minute portions of matter.

When a fluid is subjected to heat, the particles acquire energy and start moving extremely fast, causing the liquid to expand.

The much more energetic particles at the exterior getaway as vapor phase from the surface as the liquid warms.

Thus, the arrangement and movement of the particles gets disturbed when a substance is boiled, and it gets escaped as vapor.

7) Explain how the atomic number of an element identifies the element.

Answers

Answer:

The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. ... The sum of the atomic number Z and the number of neutrons N gives the mass number A of an atom.

Answer:

Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number.
