Hi, by this I assume you mean that you want to know which changes of state produces heat (raise the air temperature) as this temperature change is the removal of energy from the system. (Also called an exothermic reaction).
To remove energy from a change of state bonds must be formed between molecules therefore going from gas to liquid, gas to solid or liquid to solid are all exothermic and remove energy from the system.
If you mean removal of energy from the air therefore decreasing air temperature then it is the other way around.
What else can I help you with?
Melting gain or loss thermal energy?
Melting is a process that requires an input of thermal energy in order to overcome the forces holding the molecules together. This energy breaks the bonds between the molecules, allowing the substance to change from a solid to a liquid. Conversely, when a substance solidifies, it releases thermal energy in the form of heat.
Thermal energy for melting gain or loss?
The process of melting requires energy input, so it is a gain of thermal energy. This is because the energy is needed to overcome the intermolecular forces holding the solid together and to increase the kinetic energy of the molecules in order to transition from a solid to a liquid state.
Does vaporizing require an input or energy?
Yes, vaporizing requires an input of energy to heat the substance to its vaporization point. This energy causes the substance to change from a solid or liquid state to a vapor or gas state.
What process requires energy input?
Photosynthesis requires energy input in the form of sunlight to convert carbon dioxide and water into glucose and oxygen.
What happens when a object gains thermal energy?
When an object gains thermal energy, its molecules start to move faster, leading to an increase in temperature. This increase in temperature can cause the object to expand, change phase (from solid to liquid, for example), or even break down if the thermal energy input is too high.
The driving force of a reaction is the change in?
The driving force of a reaction is the change in free energy. This change determines whether a reaction will proceed spontaneously or require external energy input. A negative change in free energy indicates a spontaneous reaction, while a positive change requires energy input.

Melting is a process that requires an input of thermal energy in order to overcome the forces holding the molecules together. This energy breaks the bonds between the molecules, allowing the substance to change from a solid to a liquid. Conversely, when a substance solidifies, it releases thermal energy in the form of heat.

What input is necessary for the breaking of covalent bonds, which requires the input of energy?
The breaking of covalent bonds requires the input of energy. This energy can come from various sources such as heat, light, or electricity.
Does vaporizing require an input or energy?
Yes, vaporizing requires an input of energy to heat the substance to its vaporization point. This energy causes the substance to change from a solid or liquid state to a vapor or gas state.
What process requires energy input?
Photosynthesis requires energy input in the form of sunlight to convert carbon dioxide and water into glucose and oxygen.
Energy release is to condensation as energy input is to?
Energy release is to condensation as energy input is to vaporization. Vaporization requires energy input to happen, while condensation releases energy.
What happens when a object gains thermal energy?
When an object gains thermal energy, its molecules start to move faster, leading to an increase in temperature. This increase in temperature can cause the object to expand, change phase (from solid to liquid, for example), or even break down if the thermal energy input is too high.
Is evaporation energy loss or gain?
Evaporation is considered an energy gain process because it requires energy input to break the bonds between liquid molecules to change them into vapor. This energy input comes from the surrounding environment, which leads to cooling of the remaining liquid.
During which change is energy absorbed?
Energy is absorbed during an endothermic change, such as melting ice or breaking chemical bonds. This type of change requires an input of energy to overcome the forces holding the particles together.
How to find thermal efficiency in a system?
To find thermal efficiency in a system, you can use the formula: Thermal Efficiency (Useful Energy Output / Energy Input) x 100. This calculation involves determining the amount of useful energy produced by the system compared to the total energy input. The higher the thermal efficiency percentage, the more effectively the system converts energy into useful work.
What energy transforms fuel into thermal energy and electromagnetic energy?
When you burn a fuel in air you are converting chemical potential energy into thermal energy. The only energy input needed is to raise the fuel temperature to the ignition point. To obtain electromagnetic energy you have to drive a generator, which requires mechanical energy, so you have to use the thermal energy to drive a heat engine, a gas turbine is a good example.
