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 core relationship?Mathematically links pressure, volume, and temperature of a substance
2. What is the scientific disciplines?Fundamental to physics, chemistry, and engineering
3. Why did scientists create equations of state?Scientists made them to predict how things like water, air, or gases behave when they get hot, cold, or squished. This helps engineers design engines, pipelines, and even study stars.
4. How did the ideal gas law start?Early scientists Robert Boyle and Jacques Charles noticed patterns in gas behavior and wrote a rule that pressure times volume equals temperature times a constant. It worked well for simple gases but not for all real gases.

Thermodynamic State Variables: Macroscopic properties like pressure, volume, and temperature that define a system's state.
Intermolecular Forces: Attractive or repulsive forces between molecules that influence material behavior.
Statistical Mechanics: A branch of physics that uses probability to explain the behavior of large numbers of particles.
