Question

mark the checkbox for each process, depending upon whether they describe first or second law of thermodynamics. flipping on a light switch cooking an egg on the stove a lizard sunning itself on a rock an ice cube melting getting a suntan during spring break evaporation of a pan of water a nail rusting release of exhaust from the muffler of a car

Explanation:

The first law of thermodynamics is about energy conservation (energy can be transferred or transformed but not created or destroyed). Cooking an egg (heat energy is transferred to cook the egg), evaporation of water (heat energy causes a phase - change), and a nail rusting (chemical energy transformation) involve energy transfer/transformation and follow the first law. The second law is about entropy (the entropy of an isolated system always increases over time). Flipping a light switch involves energy dissipation as heat (entropy increase), an ice - cube melting (entropy increases as it goes from a more ordered solid to a less ordered liquid), a lizard sunning (entropy increases as heat is transferred and distributed), getting a suntan (chemical reactions in skin with entropy increase), and exhaust release from a car (entropy increases with heat and gas release) follow the second law.

Answer:

Flipping on a light switch: Second Law of Thermodynamics
Cooking an egg on the stove: First Law of Thermodynamics
A lizard sunning itself on a rock: Second Law of Thermodynamics
An ice cube melting: Second Law of Thermodynamics
Getting a suntan during Spring Break: Second Law of Thermodynamics
Evaporation of a pan of water: First Law of Thermodynamics
A nail rusting: First Law of Thermodynamics
Release of exhaust from the muffler of a car: Second Law of Thermodynamics
