Thermodynamics (easy)

Front

What is entropy?

Back

Entropy is a measure of the disorder or randomness in a system. It quantifies the amount of energy in a physical system that is not available to do work.

Front

Which state of matter has the highest entropy?

Back

A hot gas has the highest entropy compared to a cold solid, a hot liquid, or a cold gas.

Front

What is the Zeroth Law of Thermodynamics?

Back

The Zeroth Law states that if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.

Front

What does the First Law of Thermodynamics state?

Back

The First Law states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the Second Law of Thermodynamics?

Back

The Second Law states that the total entropy of an isolated system can never decrease over time, and is constant if all processes are reversible.

Front

What is an open system?

Back

An open system is one that can exchange both energy and matter with its surroundings.

Front

What is a closed system?

Back

A closed system can exchange energy but not matter with its surroundings.

Front

What is an isolated system?

Back

An isolated system cannot exchange energy or matter with its surroundings.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other do not exchange heat, meaning they are at the same temperature.

Front

What is the relationship between temperature and entropy?

Back

As temperature increases, the entropy of a system generally increases because the particles have more energy and move more freely.
