No, binding energy cannot be negative. Binding energy is always a positive quantity that represents the energy required to hold a system together. If the binding energy were negative, it would imply that the system is in an unstable state.
The Gibbs free energy will always be negative for a spontaneous reaction at constant temperature and pressure. This suggests that the reaction is thermodynamically favorable and can proceed without the input of external energy.
Yes. Potential energy can't be specified in absolute terms; you have to arbitrarily define a reference point. For the case of gravitation, any object below the reference point would have negative potential energy. What matters is not the number assigned to the potential energy, but the difference - this difference would be the same, even if you change your reference level.
No, potential energy is always measured as a positive value. It represents the stored energy an object has due to its position or configuration in a system. Negative values are not typically used to represent potential energy.
No, not all energy transferred during an energy change is always useful. Some energy may be lost as heat or sound, decreasing the overall efficiency of the energy transformation. This is known as energy wastage, and it occurs in many natural and human-made processes.
The enthalpy change of combustion is always negative because it involves the breaking of bonds in the reactants, which requires energy input, and the formation of new bonds in the products, which releases energy. The energy released during bond formation is greater than the energy required for bond breaking, resulting in a net release of energy, hence the negative value.
No, binding energy cannot be negative. Binding energy is always a positive quantity that represents the energy required to hold a system together. If the binding energy were negative, it would imply that the system is in an unstable state.
bcoz the energy of bound system is always negative
The hydration of an ion is negative because energy is released when water molecules surround and stabilize the ion. This release of energy is favorable and results in a negative enthalpy change. The hydration process is exothermic, meaning it releases heat.
when H is negative and S is positive
The Gibbs free energy will always be negative for a spontaneous reaction at constant temperature and pressure. This suggests that the reaction is thermodynamically favorable and can proceed without the input of external energy.

Most electron affinities are negative because when an electron is added to an atom, energy is released. This released energy causes the system to become more stable, resulting in a negative change in energy. The negative sign indicates that energy is released during the process.

A change in energy, such as heating or cooling, always accompanies a phase change in matter. This energy is required to break or form intermolecular forces between particles in order to change the physical state of the material.
Energy is always involved.
