Questions & Step-by-Step Solutions
Which law states that the total energy of an isolated system remains constant?
Correct Answer: First law of thermodynamics
Step 1: Understand what an isolated system is. An isolated system is one that does not exchange energy or matter with its surroundings.
Step 2: Learn about energy. Energy can change forms (like from potential to kinetic) but the total amount remains the same in an isolated system.
Step 3: Identify the law that describes this concept. The first law of thermodynamics is the law that states energy cannot be created or destroyed, only transformed.
Step 4: Conclude that the first law of thermodynamics means the total energy of an isolated system remains constant.
