An Elementary Text-Book of Physics, Vol. 3 of 4 (Classic Reprint) - Softcover

Inhaltsangabe

Explore the basics of heat and temperature with a clear, lecturer‑level introduction suitable for beginners. This edition presents heat as a form of energy and explains how it is produced, how temperature differs from heat, and how heat moves between bodies. It also covers how substances expand, contract, and change state as they are heated or cooled, with practical demonstrations of melting points, liquefaction, and solidification.

The book surveys key concepts such as how the sensation of warmth or cold arises from heat transfer, and how materials’ physical properties respond to temperature changes. It uses simple experiments to illustrate melting, freezing, and the behavior of gases and liquids under temperature changes, building a solid foundation for further study in physics.

• Learn how heat can come from chemical reactions, mechanical work, or electrical energy.


• See how temperature differs from the amount of heat a body contains, and how heat flows between objects.


• Understand changes of state, including melting, freezing, and vaporization, and what fixed temperatures mean for some materials.


• Explore practical demonstrations of thermal concepts through classic experiments and measurements.

Ideal for readers starting introductory physics, students preparing for elementary examinations, and anyone seeking a clear, practice‑oriented overview of heat and temperature.
