Scientific Language: Fact, Law, Theory

Front

What is the Kinetic Molecular Theory?

Back

A theory that states gases are composed of particles that behave like spherical objects in constant, random motion, explaining properties of gases such as volume, temperature, viscosity, and heat conductivity.

Front

Why are scientific theories modified?

Back

New evidence that supports a revision prompts scientists to modify earlier theories.

Front

What does the equation P1V1 = P2V2 represent?

Back

It represents a law stating that for a fixed amount of gas at constant temperature, pressure and volume are inversely proportional.

Front

What is a scientific fact?

Back

A statement that can be proven true or false based on evidence, such as 'The freezing point of water is 0 °C.'

Front

What is the difference between a scientific theory and a law?

Back

A theory explains how a natural event occurs, while a law predicts the event.

Front

What is a scientific law?

Back

A statement based on repeated experimental observations that describes an aspect of the world, often expressed mathematically.

Front

What is a scientific theory?

Back

A well-substantiated explanation of an aspect of the natural world that is based on a body of evidence.

Front

What is an example of a scientific law?

Back

Newton's Law of Universal Gravitation, which describes the gravitational attraction between masses.

Front

What is an example of a scientific theory?

Back

The Theory of Evolution, which explains the diversity of life through natural selection.

Front

What is the role of evidence in scientific theories?

Back

Evidence is crucial for supporting, modifying, or refuting scientific theories.
