♦ Relevant knowledge

If a process , whether chemical or physical one, involves the absorption or emission (taking in or exchanging) in thermal energy it’s the thermodynamics field that can explain the process. If the process absorbs heat, it’s called endothermic. If it emits heat, it is off heat, it’s called exothermic. The condition of the molecules or atoms that result from the exothermic process is that is less energy since energy was taken out of the system. In an endothermic reaction the state of molecules or atoms is with higher energy because they have added energy into the process. The chemical reaction that takes place within hand warming devices is one of those situations in which the energy gap between reactants and the products is substantial.

    Concepts and Reason

    Endothermic processes are those in which the substance’s phase changes from liquid to solid, liquid to gas, or both.

    Exothermic processes are those in which the substance’s phase changes from liquid to gas, liquid to solid, or gas to liquid.

    Fundamentals

    The exothermic process is when energy is released.

    The endothermic process refers to the process by which energy is absorbed.

    Sublimating refers to the process where the phase changes from solid into gas.

    Melting refers to the transformation of a phase from liquid to solid.

    Deposition refers to the change in phase from gas to solid.

    Vaporizing refers to the process where the phase changes from liquid into gas.

    Condensing refers to the transformation of a phase from liquid to gas.

    Freezing refers to the process by which the phase transitions from liquid to solid.

    Sublimating, melting and vaporizing all fall under the umbrella of endothermic processes, while deposition, freezing and condensing fall under the umbrella of exothermic.

    As such, you can drag the items into their boxes in the following manner:

    Exothermic process
Endothermic process
subliming
deposition
melting
condensing
vaporizing
freezing
Ans:

    As follows:

    Exothermic process
Endothermic process
subliming
deposition
melting
condensing
vaporizing
freezing
