The correct answer would be option A. The process that most likely takes place when the kinetic energy of molecules overcomes the intermolecular forces is boiling. This is because at this point the molecules are now able to escape the forces of attraction between each other in order to remain in a liquid phase.

Answer from: kotetravels10

a) boiling

Explanation:

The major difference between solids, liquids and gases is:

a) intermolecular forces [ the order is solid>liquid>gas]

b) kinetic or thermal energy. [the order is gas>liquid>solid].

thus when the kinetic energy is more and intermolecular forces are less it means there is a change from

i) solid to liquid

ii) solid to gas

iii) or liquid to gas

the given processes observe following phase changes:

a) boiling : liquid to gas

b) condensation : gas to liquid.

c) freezing : liquid to solid.

d) solidification:liquid to solid.

Answer from: Quest

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

explanation

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 $3d$ have energy higher than those in the $4 s$ orbital while lower than those of the $4 p$ orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the $4s$ orbital is therefore filled right after $3p$ orbitals and before $3 d$ orbitals.

potassium has electron configuration $[\text{ar}] 4 s^{1}$ and calcium $[\text{ar}] 4 s^{2}$ . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration $[\text{ar}] 4 s^{2} \; 3d^{1}$ 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 $ns^{2} \; (n-1) p^{1}$ and should be highlighted as well.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
