The two categorical ways of thinking about the matter are discussed in the passage are physical and chemical.
The matter has been the unit, from which everything is made up of. The passage asks about the matter has been the part of each and every physical and chemical reaction.
All the matter has an atom as its smallest building block. The elements listed in the periodic table also matter. The smallest and the biggest entity has consisted of matter.
The physical categorial way of thinking of matter involves the properties that can be sensed by the five human senses. The things that can be seen, heard, tasted, touched, and felt are all matters.
The chemical properties of the matter that result in the formation of a new matter that is irreversible in nature.

Answer:
There's no passage but I can say that matter are that ''thing'' which extend through all Universe, matter is everything. It can be seen or felt as liquid, gas or solid. This changes of its state depend on the amount of energy that is involved.
So, here is used categorical thinking because is a abstract concept that is hard to understand sometimes. It's abstract when we say that matter is all, not just what we see, but even what we don't see like ''Dark Matter'', which is the majority in the Universe.
b. 80,000 units, because total energy remains unchanged
c. 20,000 units, because total energy of the skier decreases
d. 80,000 units, because total energy of the skier decreases
Answer:
30,000 units, because total energy remains unchanged.
Step-by-step explanation:
The law of conservation of energy states that energy cannot be destroyed, it remains conserved but transforms from one form to the other form.
Hence, we can say that
Total energy = kinetic energy (KE) + potential energy (PE).
At 100 meters above
Total energy = 0 + 50000 = 50000 units.
Hence, 60 meters, total energy would be
20,000 + x = 50000 units
Finally,
x = 50,000 - 20,000
= 30,000
The energy will only transform from one form to the other but will not change.
Answer:
In a community near where we live is such as pond, forest, backyard. There are many types of interaction seen in the backyard.
A lion was running after a deer. This is a type of predation relationship in which the predator is running after prey in order to eat it.
This is because the, the he lion is a predator that will feed on the prey to them.
This interaction can be seen in the forest.
Answer:
Explanation:
One way that severe weather in the Earth's atmosphere affects the biosphere is that it can determine ones existence. Some people can survive and some will die when there is a severe storm such as flooding, tornadoes, and hurricanes.
A. The H2O is the solute.
B. The HCl is the solute.
C. TheHCL is the solvent.
D. The H2O is the solvent.
E. This mixture conducts electricity.
F. This mixture does not conduct electricity.

Answer:
The correct options are:
B. The HCl is the solute.
D. The H₂O is the solvent.
E. This mixture conducts electricity.
Explanation:
For the preparation of the HCl solution, 10 mL of HCl and 40 mL of water were mixed.
The compound that is present in the solution in a smaller ratio is the solute and the other compount -present in higher ratio- is the solvent.
So, the solute is HCl and the solvent is water (H₂O). Furthermore, water is considered as an universal solvent (for most of the polar and ionic compounds). According to this, the following options are correct:
B. The HCl is the solute.
D. The H₂O is the solvent.
Then, a condition for a solution that is able to conduct electricity is the presence of ions in the solution. When HCl is dissolved in water, it dissociates in ions according to the following equilibrium:
HCl ⇔ H⁺ + Cl⁻
The ions H⁺ and Cl⁻ are electrically charged so the solution can conduct electricity. According to this, the following option is also correct:
E. This mixture conducts electricity.
