Which of the following results in an increase in the entropy?
freezing water
cooling a solid
condensing water vapor
dissolving sugar in water

Dissolving sugar in water

Explanation: The process of cooling something will "remove" energy from any given system, which means decreasing the amount of entropy in the system. Freezing water, cooling a solid or condensing vapor are examples of cooling the given system. Also, the process of dissolution requires energy, it can be mixing with an instrument or the same solubility of sugar, and as you add energy to the system, this increases the entropy.

Answer- In the given question change of Entropy will be seen in option 4

Explanation - When sugar is dissolved in water the basic hydroxyl ions present in them, which are more in size than the water molecules will present and also these hydroxyl ions might act as a Donor as well as acceptor ions.

For different molecules of water Hence there will be a decrease in entropy at first which would counteract with increase in entropy this happens due to thermodynamics law.

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
