Answer:
D) Condensation of a gas into a solid.
Explanation:
An endothermic process is a process that absorbs heat from the surroundings.
A) Boiling a liquid.
This gives off heat to the surroundings. An exothermic process.
B) Freezing a solid.
In this process, the water releases heat to the surroundings, so it is an exothermic process
C) Condensation of a gas into a liquid.
As water vapor condenses into liquid, it loses energy in the form of heat. Therefore, this process is exothermic.
D) Condensation of a gas into a solid.
This process absorbs heat from the surrounding, hence it is an endothermic proccess.
Boiling a liquid is an endothermic process.
An endothermic reaction is a type of chemical reaction in which energy is consumed in the form of heat, so the product obtained has more energy than the reactants.
Boiling a liquid is an endothermic process, since the liquid needs heat to transition into a gaseous one.
The endothermic reaction involves an increase in enthalpy, which refers to a magnitude whose variation reveals the level of energy that a thermodynamic system exchanges with the environment.
On the other hand, when the reaction involves releasing energy in the form of heat or light, the process is called an exothermic reaction.
When a matter in a liquid state turns into a solid state (that is, it solidifies) and when a matter in a gaseous state turns into a liquid (it condenses), an exothermic reaction occurs.
Therefore, we can conclude that boiling a liquid is an endothermic process where energy is absorbed in the form of heat.
