The phase in which molecules have the least energy is the solid phase. Solid molecules are held together by intermolecular forces, such as London dispersion forces, van der Waals forces, and hydrogen bonding, which all make it difficult for molecules to move and vibrate, thus reducing the amount of energy they can achieve.
Additionally, solid molecules tend to be more packed together than molecules in other states, which further reduces the amount of energy they can have. In contrast, molecules in the gas phase have the most energy because the molecules are moving freely and can acquire higher amounts of kinetic energy.

In which state is the energy of molecules the lowest?
The energy of molecules is usually lowest in a state of equilibrium, which means that the molecules have reached a balance where the combination of forces and energies surrounding them are at a minimum.
This is typically demonstrated in various thermodynamic processes, such as when a liquid becomes a gas or when two gases come into contact with each other and form a solution. Usually, molecules have the lowest energy when they are at their lowest energy state, as determined by the Laws of Thermodynamics.
This occurs when the molecules enter a state of thermal equilibrium, where they have equal amounts of energy and no energy is either created or destroyed. In this state, the temperature, pressure and other related factors are stable and there is no more energy to be released.
In other words, the energy of the molecules has reached its lowest point.
What phase of water has the lowest energy?
The phase of water with the lowest energy is liquid water. At temperatures and pressures near the surface of the Earth, water exists mainly in a liquid state, and it requires the least amount of energy to keep in a liquid form.
In fact, at temperatures barely above freezing, the energy needed to convert liquid water to a solid or gaseous state is quite substantial. For example, for every gram of water that is converted from a liquid to a solid, about 80 calories of energy must be added in order to break the hydrogen bonds and overcome the liquid’s cohesive forces.
This amount of energy is about 80 times more than what is required to convert a gram of water from a liquid to a gas.
What is the lowest energy structure?
The lowest energy structure is the one that has the lowest potential energy. Potential energy is related to the arrangement of particles or objects and the forces between them. As a general rule, the more orderly the arrangement of particles or objects, the lower the potential energy of the structure.
This can be seen in physical structures such as crystals, where particles are arranged in specific patterns with strong bonds between them. At the molecular level, low energy structures have cohesive forces between molecules that give the structure integrity and stability.
For example, proteins, phospholipids, and nucleotides form the basis of biological structures, and the interactions between these strands give them their strength and stability. In order for a structure to be truly stable and efficient, it must maintain its low energy state, which can be achieved through the use of external forces, such as thermodynamic and electromagnetic forces.
Is the lowest energy level of a shell?
No, the lowest energy level of a shell is not the same as the lowest energy level of the atom. The lowest energy level of an atom is called the ground state, and this is the state of lowest energy for the atom.
The lowest energy level of a shell is the sublevel with the lowest energy within the shell. For example, if we consider the 1s shell, then the 1s sublevel is the lowest energy level within the 1s shell.
Another way to think about it is that the ground state of an atom is made up of all of the occupied sublevels in the atom’s electron configuration. Therefore, the lowest energy level of the atom may include sublevels from multiple shells.
Which shell has least energy and why?
The shell with the least energy is the K shell, which is the innermost energy level of an atom. This is because the electrons in the K shell are the closest to the nucleus, meaning that it takes the least amount of energy to excite them from the ground state.
Moreover, this shell contains the highest nuclear charge and the highest amount of angular momentum, both of which work to decrease the energy level of the shell. Additionally, because this shell has lower energy, it is the easiest to fill with electrons and is the most stable.
What are the states of matter from least to most energetic?
The states of matter from least to most energetic are as follows:
1. Solid – Solids have their molecules in a tight arrangement where the molecules are unable to move, making it the least energetic state of matter.
2. Liquid – Liquids are composed of particles held together by weak intermolecular forces. The particles can move around each other and have more kinetic energy than solids.
3. Gas – As the particles in a gas have the most freedom to move, they have the most kinetic energy.
4. Plasma – The particles in a plasma have the most energy as they are ionised and able to move freely around each other, making them the most energetic state of matter.
Which has more energy liquid or gas?
When talking about energy, the state of matter does not necessarily indicate which one contains more energy. Energy can be measured in terms of Joules and it is affected by two main factors, temperature and pressure.
Generally, the higher the temperature and pressure of a substance, the more energy it has. Therefore, when comparing the energy between liquid and gas states, it depends on the specific substance that is being compared.
In general, though, gases tend to have higher amounts of energy than liquids. Due to the nature of gases, particles are increasingly farther apart and collisions happen more often and with more force, leading to higher energy levels (on a molecular level).
Liquid particles, on the other hand, are much closer together, making it difficult to observe great activities or movements, resulting in lower energy.
However, while it is generally accepted that gas tends to have more energy than liquids, it is not always the case. For example, liquid helium has actually been observed to have higher energy than when it is in a gaseous form because its atoms are held together strongly by covalent bonds.
In the end, it all depends on the particular substance being compared, as well as its temperature and pressure.
What is the strongest state of matter?
The strongest state of matter is plasma. Plasma is composed of ions and electron, thus making it electrically conductive. It is the most abundant form of matter in the universe, making up over 99% of the visible universe.
Plasma is made of ionized gas and is so hot that it can actually be manipulated with the use of a magnetic field. It is the fourth state of matter and five times hotter than the sun’s surface. Plasma is extremely responsive and has been used to generate energy in welding processes, lighting, and in research laboratories.
Plasma is able to receive, store, and transmit energy in a very efficient manner, making it the strongest and most conductive form of matter.
Which state has least energetic molecule?
The state with the least energetic molecule is not easily discernable, as energy levels vary depending on the chemical make up of each molecule. The energy levels of some molecules can be measured through methods such as rotational and vibrational spectroscopy, measuring the amount of energy (in Joules) required to cause the chemical structure of a molecule to rotate or vibrate.
Generally, the more stable and symmetric the molecule, the less its energy levels.
Molecules with the lowest energies are often “singlet” molecules, have no permanent electric dipole moments, and are therefore non-polar. These molecules tend to have only one degree of freedom and therefore have a low chemical potential energy.
Examples of molecules with lower energies include methane, ammonia, carbon dioxide, oxygen and ethane.
Molecules with higher energies tend to have more than one degree of freedom, a higher binding energy, and therefore higher potential energy. Examples of this type of molecules are nitrogen dioxide, ozone, and chlorine fluoride.
In terms of states with the lowest energy molecule, it really depends on the molecules being compared as energy levels can differ greatly between different molecular species due to their composition and chemical make up.
