Intermolecular bonds become weaker
Freezing
Intermolecular bonds become stronger
Evaporation
Temperature increases
Vibration of molecules slows down
Molecules vibrate faster
Which of the above changes would be accompanied by an increase of the kinetic energy of particles in a liquid?
A, B, C, and H
A, C, D, and G
B, E, F, and H
B, C, F, and G
With an increase in the kinetic energy of the solid molecule the intermolecular bonds become weaker, temperature increases, melting and molecules vibrating faster are changes.
Kinetic energy is the form of the energy that is present in an entity in motion. When the kinetic energy is increased then the temperature of the particles increases and leads to evaporation.
The increased kinetic energy weakens the intermolecular bonds of the liquid particles and the molecules of the particles start vibrating fast.
Therefore, option b. intermolecular bonds become weak, option e. evaporation, option f. temperature increases and option h. molecules vibrate faster are the changes.

Final answer:
The changes that increase the kinetic energy of liquid particles are B, E, F, and H which correspond to evaporation, temperature increases, and molecules vibrating faster.
Explanation:
The changes that would be accompanied by an increase of the kinetic energy of particles in a liquid are evaporation, temperature increases, and molecules vibrate faster. During evaporation, molecules gain sufficient energy to overcome intermolecular forces and enter the gaseous phase. When the temperature increases, the average kinetic energy of the molecules increases, causing them to vibrate faster. Consequently, the correct answer is B, E, F, and H.
The changes that would be accompanied by an increase of the kinetic energy of particles in a liquid are B, E, F, and G.
When temperature increases, the average kinetic energy of the particles in a liquid also increases. This is represented by changes B and F. Evaporation (change E) also leads to an increase in the kinetic energy of the particles as they gain enough energy to escape into the vapor phase. Lastly, intermolecular bonds becoming weaker (change G) allows for more movement of the particles, increasing their kinetic energy.
Answer:
There are two correct choices:
Explanation:
Ideal gases are not real; ideal gases are a theoretical model used to confere a better understanding of gas properties. This model permits to predict the behavior of the gases using the ideal gas law, which is valid under certain conditions (mainly low pressure and high temperature).
Kinetic molecular theory states these basic assumptions for gases:
Those conditions are not perfected matched by real gas particles, since real gas particles do occupy a volume and interact with each other, this is real gas particles have significant volume and have more complex interactions than ideal gas particles.
Option 1 - Real gases are always hotter than the ideal gases.
Explanation
Gases that are different from ideality are called real gases because they are always hotter than the ideal gases as they are flying past each other at an extremely high speed that creates kinetic energy. Whereas idea gases have absolutely elastic collisions, this is as it has a valuable theory because it embraces the perfect concept of original gas law.
Option 2 - Real gases particles have significant volume.
Explanation
Real gases have significant volume because they have a high temperature and have a higher volume as compared to ideal gases. There is a general gas theory that is composed of several randomly crossing point particles. Several gases, for example, nitrogen, oxygen, and hydrogen can be manipulated like ideal gases within a generous immunity of the idea gas.
Option 3 - Real gases particles are smaller than an ideal gas.
Explanation
Real gas particles are smaller than ideal gas particles since they have a volume and are made up of molecules or atoms that typically take up some space than the ideal atoms. The ideal gas pattern manages to break at moderate temperatures level or greater pressures point when intermolecular energies and molecular mass enhances to be significant.
The first particles to evaporate from a liquid are those at the surface with the highest kinetic energy. These particles have sufficient energy to overcome the intermolecular forces of the liquid and become a gas.
The first particles to evaporate from a liquid are those at the surface of the liquid that have the highest kinetic energy. Evaporation is a process that occurs when particles at a liquid's surface have sufficient energy to break free of the liquid's intermolecular forces and become a gas, such as when water boils to steam. This is why sometimes we see a liquid seeming to 'disappear' over time, like a puddle drying up in the sun - it's the liquid evaporating.
Particles must have enough energy for the liquid to overcome the forces that are keeping them in the liquid. This energy is more likely to be found in particles at the surface, as they are not surrounded by other particles on all sides and therefore experience less resistance to their motion.

The correct option is False.
The first organic compound synthesized in the lab was urea. It was synthesized from silver cyanate and ammonium chloride. It is named Wöhler synthesis after the German chemist.
NH₄Cl + AgNCO → H₂NCONH₂
Urea was first synthesized in 1828 and its synthesis was the beginning of modern organic chemistry.
