When heat is absorbed during a chemical reaction, the reaction is said to be _______
When heat is absorbed during a chemical reaction, the reaction is said to be _______
- A) thermodynamic
- B) exothermal
- C) isothermal
- D) endothermic
Correct Answer: D) endothermic
Explanation
In a chemical reaction, when heat is absorbed, it means that energy is taken in from the surroundings. This type of reaction is called an endothermic reaction (Option D).For more context, let's briefly look at the other options:
Option A: Thermodynamic - This term refers to the study of energy and its transformations, and is not the name of a specific type of reaction.
Option B: Exothermal (Exothermic) - This is actually the opposite of an endothermic reaction. In an exothermic reaction, heat is released or given off to the surroundings.
Option C: Isothermal - This term is used when a process occurs at a constant temperature, meaning no heat is exchanged. It is not the name of a specific type of reaction.
Option E: Thermostatic - This term is not related to chemical reactions. A thermostat is a device that regulates temperature, and thermostatic refers to something related to or controlled by a thermostat.
In summary, when heat is absorbed during a chemical reaction, it is referred to as an endothermic reaction.
