Which of the following is an extensive property of a sample of aluminum?

Answers

Answer:

Entropy,mass and volume.... I think

Mass is the extensive property of a sample of aluminum. Therefore, option (A) is correct.

What is the extensive property of matter?

The extensive property can be described as a physical property of matter that changes with a change in the size and shape of the matter. Therefore, the extensive property of any substance varies directly with the mass.

Extensive properties are the value of the property of the system that must be equal to the sum of the values of different parts of the system. These properties depend on the amount of matter contained in the system.

Examples of Extensive properties are temperature, pressure, density, boiling point, etc. The ratio of the two extensive properties is an intensive property such as density.

The mass of a sample of aluminum is an example of extensive property as it depends on the amount of aluminum in the given sample. This property of the sample is proportional to the size of the system.

In what way do the atoms in the same row of the Periodic Table increase from left to right?

Answers

Answer:

As you move from left to right, the nucleus gains protons. This increases the positive charge of the nucleus and its attractive force on the electrons. At the same time, electrons are added to the atoms as you move from left to right across a period.

Explanation:

Scientists digging in a cave found an unknown substance. The scientists
found that the substance’s molecules were moving around each other. The scientists
increased the speed of the substance’s molecules and caused a phase change. How
did the scientists do this, and how did this affect the substance?

Answers

Answer:

By adding heat energy

It became a gas

Explanation:

The molecules moving about another is a clear indicator that the substance is a liquid.

In a liquid, the molecules stick together and move about one another.

When the scientist increase the speed of the of substance, the kinetic energy increases. if this increase causes a phase change, then the substance becomes a gas. So, by adding heat energy a substance becomes gaseous if it is a liquid already.

what would happen if the
attractive forces between all of the particles
of matter on Earth were equal?

Answers

Either everything would solid (strong attractive force), liquid or gas (weaker attractive force). Everything would be the same matter

The magnitude of attractive forces between particles that compose matter determine the state of matter. Hence, if all particles of matter on earth have equal attractive forces, only a single state of matter (solid, liquid or gas) will exist on earth.

Matter exists in three states;

SolidLiquidGas

In solids, there exists the greatest magnitude of attractive forces between particles.

There are weaker inter-molecular attractive forces between liquid particles. However, inter molecular attractive  forces are almost non-existent in gases.

The reason for the existence of different states of matter on earth is difference in magnitude of inter molecular attractive forces in each state of matter.

If all particles of matter possess equal attractive forces, only one state of matter will be found on earth; either solid, liquid or gas.

The best model of weathering is using a fan on a pile of sand causing the sand to move into a pile in a new location.

Weathering refers to the gradual breakdown of a rock due to the agents of denudation. The agents of denudation could be physical, chemical or biological.

The breakdown of rocks leads to the formation of soil. The closest model to the weathering of rock is using a fan on a pile of sand causing the sand to move into a pile in a new location.

The pile represents the rock which is being broken down as the fan blows the pile and it settles on a new location.

Which describes how rubbing fur on a rubber rod makes the rod negatively charged. Select one: A. Electrons move from the fur to the rubber rod. B. Electrons move from the rubber rod to the fur. C. Protons move from the rubber rod to the fur.

Answers

Answer:

A

Explanation:

Rubbing fur on a rubber rod results in the rod becoming negatively charged as a result of the movement of electrons from the fur to the rubber rod.

The process is called triboelectric charging.  When the two substances are rubbed together, their atoms come into close proximity with each other and their electron clouds interact with the fur losing electrons to the rubber due to the fact that the atoms of the rubber have higher affinities for electrons than the atoms of the fur. Hence, the fur becomes positively charged while the rubber becomes negatively charged.

Answers

Answer:

option A: Atomic number

Explanation:

The atoms, isotopes and ions of magnesium doesn't change the atomic number of the magnesium.

For example, Isotopes are atoms that have the same number of protons but at the same time have different numbers of neutrons. This means that atomic number remains the same while mass number differs. Now, an ion is defined as an atom or molecule that has either a positive or negative charge.

So only option A is correct: Atomic number
