# Ch 11: Thermodynamics in Physics

Watch video lessons on thermodynamics in physics and learn about temperature units, phase changes, heat transfer, thermal expansion and more. These video lessons are short and engaging and make learning easy!

## Thermodynamics in Physics - Chapter Summary and Learning Objectives

This chapter focuses on heat transfer and uses for the first and second laws of thermodynamics. You'll learn how to convert between Kelvin and Celsius and interpret a heating curve, then see examples for heat transfer through conduction and convection. Instructors will introduce you to the Ideal Gas Law and provide step-by-step instructions for calculating entropy of a closed system. When you've watched all the lessons in this chapter, you'll have knowledge of:

• Relationship between temperature and heat
• Events during a phase change
• Importance of thermal expansion
• Gas constant
• Heat engines
