Thermodynamics is a very important branch of science and engineering that studies the role of heat and its relation to energy and work. This course introduces you to the core concepts of thermodynamics such as the relationship between pressure, volume, and temperature and how changes in one can affect the others. You will also look at examples and solve certain problems in order to help you better understand the concept of thermodynamics.

Thermodynamics is the branch of physics that describes how thermal energy is converted to and from other forms of energy and how it affects matter. This course will first discuss the essential properties of gases and liquids. You will learn that an ideal gas has a pressure and temperature and is in a container with volume. If the temperature increases, the pressure can be kept constant by increasing the pressure of the container.

Temperature is defined as the average kinetic energy per molecule in a sample of matter and is expressed in terms of units or degrees designated on a standard scale. This course will teach you how temperature affects pressure and volume. You will learn that absolute zero is equivalent to -273 degrees Celsius and study how to calculate absolute zero and degrees Celsius in degrees Kelvin. You will also study the mole and Avogadro's Constant.

The study of thermodynamics is important to help you understand the relationship between work, heat, and energy. You will learn how to convert energy from one form to another and the interaction of a system and its surroundings. It is also essential for working in many scientific and engineering disciplines such as physics, chemistry, chemical engineering, petroleum engineering, and materials science. So, check out this course and expand your knowledge of physics today!
