What is cohesive energy of a molecule?
To calculate the cohesive energy, let us consider the general situation of two identical atoms. As the atoms approach, the attractive forces increases and potential energy decreases. At the equilibrium position the potential energy of either two atom is given by U= decrease in potential energy due to attraction + increase in potential energy due to repulsion. work done in moving through a small distance dr is given by du(r) + F(r)dr Hence the potential energy if the atom U(r)=int du(r) = int F(r)dr = int(A/rM - B/rN)dr
What is an energy conversion diagram?
An energy flow diagram is normally a flow diagram showing the energy gains and energy losses of a given process. This type of diagram is often used to show the efficiency of a given system or lack thereof.
Kinetic energy of particles?
Kinetic energy of particles is the energy associated with their motion. It is given by the formula KE = 1/2 mv^2, where m is the mass of the particle and v is its velocity. The greater the mass or velocity of a particle, the greater its kinetic energy.
How does energy transfer with the sound wave?
The transfer of energy in sound wave is by the atoms of that medium. When mechanical energy is given by our mouth in the atoms near the mouth, the atoms gain the mechanical energy and convert it into kinetic energy and begin to move within their mean positions and while moving they hit each other and the energy is is transferred to the other electron and this process continues until due to some factors the energy is transferred and heard by an observer at the other end. Sound waves require a material medium for their transmission. The transfer of energy in sound will not occur in a vacuum.
What type of energy is given off with the heat energy?
What type of energy is given off with the heat energy?
How might improvements in technology for producing a given energy resource affect its net energy?
It improves energy conversions
Nuclear energy is energy given during the fusing or splitting atomic nuclei?
Yes, both
The energy and particles given off during a nuclear reaction are called?
Radiation
What is. the collective name of high-energy particles and rays given off by the nuclei of atoms?
The energy is called nuclear radiation, high energy particles and rays that are emitted by the nuclei of some atoms.

What happens to energy when carbon and oxygen atoms combine?
When carbon and oxygen atoms combine to form carbon dioxide, energy is released. This energy comes from the bonds being formed between the atoms during the chemical reaction.
What is the energy stored in th nucleus of atoms?
It depends on the atomic number and the mass number of the given atom.
When is energy given off by most nonmetals?
Energy is typically given off by nonmetals when they undergo chemical reactions such as combustion, oxidation, or when bonds between atoms are formed. This release of energy occurs as the nonmetal atoms become more stable by achieving a full outer electron shell.
How do you calculate energy-level difference when the relative population of the atoms is given?
relative population of atoms in two energy levals E1 and E2 is 10-20 calculate the enery level difference in eV. assume T=300K.

When 2 atoms combine to form a molecule energy is always absorbed always released never absorbed or released sometimes absorbed and sometimes released?
When 2 atoms combine to form a molecule, energy can be either absorbed or released, depending on the specific atoms involved and the type of bond being formed. This process can result in either an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed).
