What molecules would you expect to have the most free energy per gram?

Apart from ATP, which enables our energy functions, the answer to your question is less absolute.
Sugar/s would possibly hold the palm if only because there are so many of them overall. Or at least the carbohydrate and hydrocarbon group, simply because of their total mass.
If you're thinking of the energy bound in the atomic structure itself, the answer is different again.

What makes solids melt?
When we heat a solid, the energy is transferred to the molecules, and to the bonds between the molecules. Eventually, the bonds become broken and the molecules become free to move about. Just as in a liquid.
How is sound energy and thermal energy alike?
Temperature is what is used to measure thermal energy The more thermal energy a substance has, the more warmer it will be. So when the temperature is high, there is a lot of thermal energy Thermal energy is just energy. It refers to the energy of the molecules. Temperature is just a measurement
What does water need energy for to become water vapor?
Intermolecular forces, i.e. hydrogen-bonds, have to be broken down in order for water molecules to escape to the vapor phase. Energy is needed in the process to set water molecules free.
How does thermal energy differ from temperature?
Thermal energy refers to the total change in energy of an object as temperature changes while temperature tells us only about the change in kinetic energy of the constituent atoms and molecules. The temperature of an object is a direct measure of the kinetic energy of the atoms and molecules that make up the object. The connection between the temperature and average translational kinetic energy of atoms and molecules in a material is given by an equation, KE(averaged)=3/2kT, where the kinetic energy is the usual one half mass times velocity squared of all the molecules or atoms in a material at the temperature T. T is measured as the temperature above absolute zero. The letter k stands for the Boltzmann constant. In addition to translational kinetic energy, there is also rotational kinetic energy and vibrational kinetic energy in molecules. Those too are simply proportional to temperature with a similar equation. Thermal energy is more than kinetic energy. It also includes potential energy. In a solid, there is also electronic energy to be considered. If the material is not a simple collection of atoms and molecules, thermal energy may also include energy associated with chemical changes. In summary, we normally use the term thermal energy to describe the energy acquired by an object when heated. Temperature, on the other hand, is simply related only to that part of the energy associated with the motion of the atoms and molecules, i.e. the kinetic energy as described above. Caveats: 1. This answer ignores quantum effects that alter the relationship to kinetic energy at extremely low temperatures, near absolute zero. It ignores extremely high temperature effects where normal matter may be transformed in the plasma state. What is said here is correct for normal materials encountered by people in everyday life. 2. One should properly be discussing so-called "free energy" such as Helmholtz free energy or Gibbs free energy, but that is more in the technical arena of thermodynamics.
How do solid and liquid water change to water vapour?
Sufficient energy is added to the molecule to break the inter-molecular bonds. First, in a solid, as energy is added, the bonds absorb the energy, and move more vigorously. So our solid heats up, and eventually, the bonds are broken completely free. We now have a liquid. As energy is added to the liquid, individual molecules absorb enough energy to break free of the surface, and evaporate off into space.
What can ATP be described as?
The energy carrying molecules in living cells.
How are organic molecules broken down by catabolic pathways?
represent the difference between free energy content of the reaction and the free energy content of products?
Do molecules move in motionless liquids?
Yes They Do...In A Solid Molecules Have No Energy And Are Blocked Together...In A Liquid They Have Some Energy So They Move Abit Free-er And In A Gas They Have Loads Of Energy So They Fly About Really Free. yes. molecules can move in any substance, solid, liquid, or gas.
Explain the particle arrangement in solids liquids and gasses and energy associate with each phase?
Solids have closely-packed molecules, and very little energy Liquids have loosely-packed molecules and some energy, and gasses have very lose, free molecules, and very high energy.

Explain why you would or would not expect significant ionization in the flame?
If the test agent have free ions the ionization of the flame will be significant. When the energy reaches a point when it take more energy the flame ionization will not be significant.

In order for NAD plus to remove electrons from glucose or other organic molecules what must be true?
the free energy liberated when electrons are removed from the organic molecules must be greater than the energy required to give the electrons to NAD+

A chemical reaction such as cellular respiration that releases free energy?
glucose and other food molecules
What occurs during a light reaction?
Light is a form of energy. Light energy can be used to initiate chemical reactions. For instance light can be used to break chemical bonds homolytically, that is to say break the chemical bonds in a molecule to form free radicals. Free radicals are more reactive than the molecules from which they have formed because they possess more energy. These free radicals can then interact to produce new molecules, new products.
