Ch 19: MTEL Physics: Atomic Nature of Matter & Relativity

About This Chapter

The MTEL Physics preparation you get from this chapter revolves around questions you could see dealing with the atomic nature of matter and relativity. The key topics are examined with text and video lessons.

MTEL Physics: Atomic Nature of Matter & Relativity - Chapter Summary

Check your familiarity with the theories of general and special relativity in this chapter during your exam prep. The chapter also delves into the following lesson topics that help you get ready for the MTEL Physics test:

  • The Bohr model and atomic spectra
  • Millikan's oil drop experiment
  • The ideal gas law and calculations
  • Kinetic theory of matter
  • Rutherford's model of the atom

The knowledge you already have with these topics will be reinforced with the study resources in this chapter. Text lessons use key terms in bold to indicate the most notable content concepts.

Objectives of the MTEL Physics: Atomic Nature of Matter & Relativity Chapter

The MTEL Physics exam evaluates the degree of your subject knowledge for teaching licensure in Massachusetts. The exam's multiple-choice subarea on modern physics has between 13 and 15 questions and some ask about the development of the atomic theory and influential experiments. Info in this chapter may also show up in the final subarea of the exam since that section doesn't have a set subject matter concentration. Practice quizzes in the Atomic Nature of Matter & Relativity chapter accurately depict the kinds of questions that are on the test.

8 Lessons in Chapter 19: MTEL Physics: Atomic Nature of Matter & Relativity
The Kinetic Theory of Matter: Definition & The Four States of Matter

1. The Kinetic Theory of Matter: Definition & The Four States of Matter

Everything on Earth is made of matter, but that matter isn't always the same. Matter can exist in four different phases, and the kinetic theory of matter helps us understand the differences between those phases.

The Ideal Gas Law and the Gas Constant

2. The Ideal Gas Law and the Gas Constant

Have you ever wondered why the pressure in your car's tires is higher after you have been driving a while? In this lesson, we are going to discuss the law that governs ideal gases and is used to predict the behavior of real gases: the ideal gas law.

Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas

3. Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas

In another lesson, you learned that the ideal gas law is expressed as PV = nRT. In this video lesson, we'll go one step further, examining how to rearrange the equation to solve for a missing variable when the others are known.

Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

4. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

Imagine firing a bullet at a piece of tissue paper and having it bounce back at you! You would probably be just as surprised as Rutherford when he discovered the nucleus. In this lesson, we are going to travel back in time and discuss some of the major discoveries in the history of the atom.

Robert Millikan: Biography, Atomic Theory & Oil Drop Experiment

5. Robert Millikan: Biography, Atomic Theory & Oil Drop Experiment

Learn about the life and achievements of American physicist Robert Millikan. His oil drop experiment helped to quantify the charge of an electron, which contributed greatly to our understanding of the structure of the atom and atomic theory.

Rutherford Model of the Atom: Definition & Diagram

6. Rutherford Model of the Atom: Definition & Diagram

Though it is no longer the most accurate representation of an atom, at the time Rutherford's model was revolutionary. Learn about the development of the model of the atom and how it changed throughout history, then assess your knowledge with a quiz.

The Bohr Model and Atomic Spectra

7. The Bohr Model and Atomic Spectra

Do you ever wonder where light comes from or how it is produced? In this lesson, we are going to use our knowledge of the electron configurations and quantum numbers to see what goes on during the creation of light.

General and Special Relativity: Theory and Examples

8. General and Special Relativity: Theory and Examples

Special relativity accounts for the constant speed of light in the absence of surrounding mass. General relativity utilizes the concept of space-time to explain the effect of gravity on the speed of light. This lesson compares special and general relativity and provides examples of how the speed of light is affected by gravity.
