The energy of motion predominates in gases, whereas the energy of attraction between particles predominates in solids. In contrast to gases, which lack both defined volume and shape, solids have both.

What do you mean by solid?
One of the three fundamental states of matter, along with liquid and gas. (Ionized gases or plasmas are occasionally regarded as the fourth state of matter.) Because the energy of atoms lowers when they occupy a reasonably organized, three-dimensional structure, a solid develops from a liquid or gas. Solids differ from liquids and gases in that they have certain properties. For instance, all solids can withstand forces that are parallel or perpendicular to a surface (i.e., normal or shear loads, respectively). These characteristics are influenced by the atoms that make up the solid, their arrangement, and the forces that exist between them.

Answer:
Benzaldehyde is less electrophilic than acetaldehyde
Explanation:
Electrophilicity of carbonyl carbon depends on it's positive charge density.
In benzaldehyde, phenyl group can act as an electron donating group towards carbonyl group due to it's electron donating resonating effect.
In acetaldehyde, methyl group can act as an electron donating group towards carbonyl group due to it's electron donating inductive effect.
We know that resonating effect are more stronger than inductive effect.
Henece, it is expected that positive charge density on carbonyl carbon is much lower in benzaldehyde than acetaldehyde.
So, benzaldehyde is less electrophilic than acetaldehyde.
Resonating effect of phenyl group has been shown below.
Answer:
B
Explanation:
The other answers dont make any sense.
C. Protons
Protons are subatomic particles found in the nucleus and carry positive electrical charge.
The answer is E.
Hope it helps.
