Name Game
• You will learn better and have more fun if you know your classmates’ names.
• I will teach you better if I know your name and learn something about you.
• Say your name – be LOUD and CLEAR• Then say the name of everyone who has already
said their name…in order.• I will go last…the hardest spot.• Not enough time today. We will do the Name
Game in the Quiz Section tomorrow.

How Does Thermo Affect You ?
• Engines: Trains, Planes & Automobiles• Heating Systems: Heat Pumps• Cooling Systems:
– Air Conditioning
– Refrigeration
• Others:– Aspects of Thermo that are beyond the scope of this
course make it a key aspect of chemical and biological systems
