Chapter Summary

--- PAGE 1 --- CHAPTER TEN THERMAL PROPERTIES OF MATTER 10.1 Introduction 10.2 Temperature and heat 10.3 Measurement of temperature 10.4 Ideal-gas equation and absolute temperature 10.5 Thermal expansion 10.6 Specific heat capacity 10.7 Calorimetry 10.8 Change of state 10.9 Heat transfer 10.10 Newton's law of cooling Summary Points to ponder Exercises Additional Exercises 10.1 INTRODUCTION We all have common sense notions of heat and temperature. Temperature is a measure of 'hotness' of a body. A kettle with boiling water is hotter than a box containing ice. In physics, we need to define the notion of heat, temperature, etc., more carefully. In this chapter, you will learn what heat is and how it is measured, and study the various processes by which heat flows from one body to another. Along the way, you will find out why blacksmiths heat the iron ring before fitting on the rim of a wooden wheel of a horse cart and why the wind at the beach often …

Did you know?

• 💡 Geothermal energy from Earth's core heats homes using underground steam.
• 💡 Absolute zero is the coldest possible temperature, where atoms nearly stop moving.
• 💡 The Kelvin scale has no negative temperatures because zero Kelvin is absolute zero.
• 💡 Railroad tracks expand significantly in summer, requiring gaps to prevent buckling.
• 💡 Space suits use multiple layers to reflect heat and protect astronauts.
