Thermodynamics First and Second Law Flashcards

What does the First Law of Thermodynamics state?

What happens to the quality of matter/energy over time according to the Second Law of Thermodynamics?

Entropy is a measure of usable energy within a closed system.

The Second Law of Thermodynamics is often referred to as the law of increased _____ .

Match the following terms with their definitions:

First Law of Thermodynamics

Represents the law of conservation of matter and energy.
Asserts that matter and energy cannot be created or destroyed, only transformed.
The total quantity of matter and energy in the universe remains constant regardless of transformations (solid, liquid, gas, plasma).

Second Law of Thermodynamics

Introduces the concept of increased entropy in a system.
While total energy remains constant, the quality and usability of that energy degrades over time.
Usable energy is utilized for processes such as productivity, growth, and repair, but is gradually converted into unusable forms.
As usable energy is dissipated, it results in a loss of effective energy for work.

Entropy

Defined as the measure of unusable energy within an isolated system, including the universe.
As usable energy diminishes and unusable energy increases, entropy levels rise.
Serves as an indicator of disorder, randomness, or chaos within a closed system.
Increased entropy correlates with heightened disorganization and unpredictability as usable energy is expended.

This quiz covers key concepts related to the First and Second Laws of Thermodynamics. Understand the law of conservation of matter and the implications of entropy in thermal systems. Perfect for students looking to solidify their grasp of thermodynamics principles.
