Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

https://smallwhale.org/articles/deposition-phase-transition

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the thermodynamic pathway?Direct transition from gas to solid, bypassing the liquid phase
2. What is the thermodynamic inverse?The reverse process is sublimation (solid to gas)
3. What is deposition in simple words?Deposition is when a gas turns directly into a solid, like when water vapor becomes frost on a window.
4. Why does a gas become a solid without becoming liquid?When the gas cools enough and its pressure is high, the molecules slow down and stick together, forming a solid.

Thermodynamic Process: A change in the state of a system governed by principles of heat, work, and energy.
Phase Transition: The transformation of a substance from one state of matter to another.
Sublimation: The direct transition of a substance from solid to gas phase without passing through the liquid phase.
