Q: In thermodynamics, what does the first law of thermodynamics state?
Solution:
The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.
Steps: 5
Show Steps
Step 1: Understand that energy is a property that can exist in different forms, like heat, light, or mechanical energy.
Step 2: Recognize that the first law of thermodynamics is about the conservation of energy.
Step 3: Learn that this law states energy cannot be created from nothing or completely disappear.
Step 4: Realize that energy can only change from one form to another, like turning chemical energy in food into kinetic energy when you move.
Step 5: Conclude that the total amount of energy in a closed system remains constant, even though it may change forms.
