Therm-- Heat

Dynamics-- flow

Branch of Chemistry which deals with the study of the flow of energy is called as Thermodynamics.

What you have to do to make this flow of topic smooth and easy for you is to watch the videos one by one in the order they are posted and follow the rules of the game:

Keep a pen and paper handy with you so as to take down the points

• No more than one video at a time-- you don't want to HEAT yourself up so early 😊

• Take a short break when the video is long or the topic involves a lot of new terms.

• DEEP BREATHING during break times helps in the flow of energy and fresh O₂ to the cells of the body and keeps your mind fresh.

There are 18 videos in all in this topic.Some may not be required as per your curriculum, so feel free to ignore them or just browse through them to keep the continuity of the topic.

Part 1- Basic terms used in thermodynamics. If you want to have a clear understanding of the topic then do not miss this video at any cost. It deals with the basic terminology in thermodynamics :

• System / surrounding

• Open / closed / isolated system

• Types of process --- Isothermal, Adiabatic, Isochoric, Isobaric, Cyclic

• Properties-- Extensive and Intensive

Part 2

Internal Energy and its characteristics

Part 3

Work and its forms.

Work done under various conditions

Part 4 : Heat and it's characteristics

Types of specific heats--- Cp and Cv and the relation between them.
