First Law of Thermodynamics


A video lecture titled, ‘Basic Thermodynamics’ from the e-learning course, ‘Introduction to Atmospheric Science’ developed by C Balaji, IIT Madras, for National Programme on Technology Enhanced Learning (NPTEL), India. This video lecture explains and details the first law of thermodynamics (Q – W = Delta E) in the context of atmospheric science.

Students will be introduced to the first law of thermodynamics. They will further be introduced to terms such as adiabatic and isothermal processes and related equations and methods of calculating geo-potential thickness using Radiosonde data.

Use this tool to help your students find answers to:

  1. State the first law of thermodynamics with the equation.
  2. State the relationship between pressure and volume.
  3. Discuss the first law of thermodynamics with respect to Earth’s atmospheric system.
