Answer:
Lithuim is the smallest
Explanation:
i hope this helps!!
Atom is the most basic unit of matter. They are the general term used to describe pieces of matter. But a different kind of atom makes up an element. A combination of atom of different elements creates a molecule. For example, you have water; it has a chemical formula of H2O. If you separate H from O, you have two atoms. Two atoms for hydrogen and one atom for oxygen. However, they are of different elements. And when you combine them to form H2O, you create a molecule.
A. motion of particles.
B. density of particles.
C. randomness of particles.
D. kinetic energy of particles.
Answer: is C
Explanation:
The most appropriate label for the y-axis in a graph comparing states of substances would be related to changes that occur in different states of matter, such as kinetic energy or motion. The label 'density of particles' would not be appropriate, as it doesn't significantly vary between states.
The appropriate label for the y-axis on a graph that compares three states of a substance might typically be something directly related to those states, such as kinetic energy of particles, motion of particles, or randomness of particles. These labels reflect changes that occur in different states of matter. When substances change state, there are changes in the arrangement and motion of the particles.
By contrast, density of particles would not be an appropriate label. Density, in this sense, is not a property that varies significantly between different states of a substance. The density of a substance in its solid, liquid, or gaseous state does not refer to the density of the individual particles themselves, but to the density of the substance as a whole (mass/volume).

Scientists believe it is the best explanation because it is built on data and observations.
The majority of the scientific community voted on this theory over other possible explanations.
It is the best explanation because it supports the beliefs and opinions of most scientists.
It is a scientific law that has been supported by experimental data.
Answer:
The correct answer will be option-It is the best explanation because it supports the beliefs and opinions of most scientists.
Explanation:
Albert Einstein is known for his theory of relativity which states that energy is a converted form of mass to the square of the speed of light which is constant.
Albert Einstein was a theoretical physicist who used the facts and data from the papers of the previous physicist. Although he used the facts his theory became one of the important theory in the physics world as it explained the path of the light and the form in which it travels.
This theory is well accepted today as it was supported by the experiments and observation of the other works of different scientist. This led to the acceptance of the theory worldwide.
Thus, the selected option is the correct answer.
B. anger
C. bargaining
D. depression
b.) Find the density of the rock dropped into the graduated cylinder.
Answer:
Explanation:
Answer:
Explanation:
A. Volume
The volume was found using water displacement. Subtract the initial volume from the final volume.
The graduated cylinder had 20 milliliters of water (initial volume).
After the rock was added, the graduated cylinder read 30 milliliters (final volume).
Substitute the values in and subtract.
The volume of the rock is 10 milliliters.
B. Density
Density can be found by dividing the mass by the volume.
The mass of the rock is 23 grams. We just found the volume of 10 milliliters.
Substitute the values in and divide.
The density of the rock is 2.3 grams per milliliter.
Answer:
Volume = 10 cm3
Density = 2.3g/cm3
Explanation:
volume:
30ml - 20ml = 10ml = 10cm3
density:
density = mass/volume
23/10
2.3g/cm3
