Answer:
greenhouse effect
Explanation:
Greenhouse effect -
It is the process by which the radiations on the planet gets trapped inside its atmosphere and increases the temperature of the planet , is referred to as the process of greenhouse effect .
Few gases are responsible to show this process , like carbon dioxide . methane , water vapour etc.
The process of greenhouse is important for the planet to sustain life , as it makes the planet warm and thereby don't allow the planet to freeze ,
But excess of greenhouse effect can make the planet extremely warm , and lead to a condition of global warming .
Hence , from the given information of the question ,
The correct answer is greenhouse effect .

(1) decreases
(2) increases
(3) remains the same
Answer: Option (1) is the correct answer.
Explanation:
Kinetic energy is the energy that arises due to the motion of molecules. Average kinetic energy involves the sum of vibrational, translational and rotational kinetic energies.
When we decrease the temperature then the movement of molecules starts to decrease. As a result, there will be decrease in the average kinetic energy of its particles.
Thus, we can conclude that as the temperature of a substance decreases, the average kinetic energy of its particles decreases.
The boiling point of an aqueous solution is elevated due to the presence of a nonvolatile solute. The extent of the boiling point elevation depends on the total number of solute particles in the solution. The solution with the highest boiling point would be 0.100 m AlCl3 because it breaks down into the most ions in solution.
The subject of this question is boiling point elevation, a chemical concept that is most relevant to the field of chemistry. The boiling point of an aqueous solution is elevated due to the presence of a nonvolatile solute because the solute lowers the solution's vapor pressure, requiring a higher temperature for the solution to boil. The extent of the boiling point elevation depends on the total number of solute particles in the solution, rather than their individual properties such as mass or chemical identity.
Given the choices of 0.100 m C6H12O6, 0.100 m AlCl3, 0.100 m NaCl, and 0.100 m MgCl2, the solution with the highest boiling point would be 0.100 m AlCl3. This is because AlCl3, aluminum chloride, breaks down into four ions in solution (one Al3+ ion and three Cl- ions), whereas the other substances break down into fewer ions (C6H12O6 doesn't break down into ions at all, NaCl breaks down into two ions, and MgCl2 breaks down into three ions). The more ions a substance breaks down into, the higher the elevation of the solution's boiling point.

Among the given solutions, the 0.100 m AlCl3 (aluminum chloride) solution should have the highest boiling point as it produces the most particles when it dissociates in the solution, according to the principle of 'boiling point elevation'.
The question asks to choose the aqueous solution with the highest boiling point among 0.100 m C6H12O6 (glucose), 0.100 m AlCl3 (aluminum chloride), 0.100 m NaCl (sodium chloride), and 0.100 m MgCl2 (magnesium chloride). The highest boiling point will be determined by the solution with the most particles, because as the number of particles increase, the boiling point will rise. This concept is part of 'boiling point elevation' in solutions.
Both NaCl and MgCl2 will dissociate into ions when dissolved in water, producing 2 and 3 particles respectively for each formula unit. Meanwhile, AlCl3 will produce 4 particles when it dissociates (Al3+ and three Cl- ions). Glucose is a covalent compound and will not dissociate when dissolved in water; hence it only counts as one particle.
Based on the number of solute particles, AlCl3 should have the highest boiling point as it produces the most particles when it dissociates in the solution.

Protons: 11 - Neutrons: 12 - Electrons: 11. By analyzing the atomic number, mass number, and net charge, we can determine the number of protons, neutrons, and electrons in the sodium-23 atom.
The sodium-23 atom (Na-23) has a net charge of +1, which means it has one more proton than electrons. To determine the number of protons, neutrons, and electrons in the atom, we need to look at its atomic number and mass number.
The atomic number of an element represents the number of protons in its nucleus. Since the net charge of the sodium-23 atom is +1, it means there is one more proton than electrons. Therefore, the number of protons in the sodium-23 atom is 11.
The mass number of an atom is the sum of its protons and neutrons. To find the number of neutrons, we subtract the number of protons (atomic number) from the mass number. In this case, the sodium-23 atom has a mass number of 23, and since it has 11 protons, we can calculate the number of neutrons:
Mass number - Atomic number = Number of neutrons
23 - 11 = 12 neutrons
Lastly, to find the number of electrons, we need to consider the net charge. Since the sodium-23 atom has a net charge of +1, it means it is missing one electron to become neutral. Therefore, the number of electrons in the sodium-23 atom is 11.
In summary:
- Protons: 11
- Neutrons: 12
- Electrons: 11
By analyzing the atomic number, mass number, and net charge, we can determine the number of protons, neutrons, and electrons in the sodium-23 atom.
