Question
When a living organism dies, why does it become cold?
A. because all of the internal chemical reactions have stopped so no heat is being released
B. because there are too many chemical reactions taking place
C. because the chemical reactions inside of it are speeding up faster and faster
Solution
The correct answer is A. When a living organism dies, it becomes cold because all of the internal chemical reactions have stopped so no heat is being released.
Here's a step-by-step explanation:
-
While an organism is alive, it maintains a process called metabolism. Metabolism is a series of chemical reactions that occur within a cell to maintain life. These reactions generate heat as a byproduct, which helps to maintain the organism's body temperature.
-
When an organism dies, these metabolic processes cease. Without these ongoing chemical reactions, no new heat is generated.
-
As a result, the heat that was already present in the organism's body begins to dissipate into the surrounding environment. This is a process known as cooling.
-
Over time, this cooling will cause the organism's body temperature to drop, making it feel cold to the
