Change of phase from gas to liquid to solid are exothermic reaction. Condensation, deposition and freezing are exothermic processes that undergo change in phase.

You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
The conclusion phase of the decision making process results in one of two things. Either the problem is resolved or the failure leads to a return to a previous phase.
Identification phase which begins with recognition. The development phase where a solution is shaped to solve the problem and the selection phase when the solution is chosen.
i need help with this one as well
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
condensation freezing and deposition
Yes, the process of liquid mercury changing to a vapor is exothermic. This means that heat is released during this phase change.
The phase change of sublimation is not correctly paired with the sign of its change in enthalpy. Sublimation involves the transition from solid to gas phase without passing through the liquid phase, and it is an endothermic process where heat is absorbed. The other phase changes—melting (endothermic), freezing (exothermic), vaporization (endothermic), and condensation (exothermic)—are correctly paired with the sign of their change in enthalpy.
A solid is itself neither endothermic or exothermic. However the phase change from liquid to solid will likely be exothermic.
Solid to liquid (melting): This phase change requires energy to break the intermolecular forces holding the solid together, resulting in an endothermic process. Liquid to gas (vaporization): This phase change requires energy to overcome the intermolecular forces between liquid molecules, also an endothermic process. Gas to liquid (condensation): This phase change releases energy as gas molecules lose kinetic energy, forming stronger intermolecular forces in the liquid phase, and is an exothermic process.
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Sublimation is an endothermic process because it requires energy input to change a substance from a solid directly to a gas without passing through the liquid phase.
The melting of a candle is an endothermic process because heat is required to break the intermolecular forces holding the solid wax together and convert it into a liquid. Energy is absorbed during this phase change.
Yes, the formation of ice crystals on a window is an exothermic process. When water vapor in the air comes into contact with the cold surface of the window, it loses heat energy and undergoes a phase change from a gas to a solid, releasing heat in the process.
The process of making Jello is an exothermic change because energy is released in the form of heat as the gelatin sets and solidifies.
Anions are not associated with either exothermic or endothermic processes on their own. The classification of a process as exothermic or endothermic depends on the overall energy change of the reaction in which the anion is involved.
