, INTRODUCTION
Thermodynamics is the study of energy, heat, and how they affect
matter. It helps us understand why things heat up, cool down, and how
energy is transferred between systems. This science is fundamental in
everyday life and various fields like engineering, chemistry, and
environmental science.
1.1 WHAT IS THERMODYNAMICS?
Thermodynamics comes from Greek words meaning "heat" and
"power." It's all about understanding how energy works and how it
moves between different forms, like heat and work.
1.1.1 THE BASICS
Energy: The ability to do work or cause change.
Heat: A form of energy transfer due to temperature difference.
Work: The process of energy transfer by force causing
movement.
1.2 WHY IS THERMODYNAMICS IMPORTANT?
Thermodynamics helps us solve practical problems, like designing
engines, refrigerators, and even understanding weather patterns. It
explains why energy can't be created or destroyed, only converted from
one form to another.
1.2.1 EVERYDAY EXAMPLES
Cars and Engines: Thermodynamics helps engineers design
engines that convert fuel into motion.
, Refrigerators: It explains how refrigerators keep food cool by
moving heat from inside to outside.
Cooking: When you cook, you're transferring heat energy to
food, causing chemical changes.
