About :
Colligative properties, let's understand how they relate to our daily lives and ENEM problems. In this class, you will discover how increasing altitude, using a pressure cooker, preparing jerked meat and even cooking cod are interconnected by surprising chemical principles, including tonometry, cryometry, ebulliometry and osmometry. Topics Covered: What are colligative properties? - An introduction to understanding what they are and why they are important. Vapor pressure and the pressure cooker - We will explore how pressure is related to the boiling point of water and how the pressure cooker benefits from this in the kitchen. The effect of altitude - Discover how atmospheric pressure influences melting and boiling points, impacting the cooking time of food and even the flavor of the food. Jerked meat - Learn how preserving meat through desiccation relates to colligative properties, making it a traditional food in several regions of the world. Cod and salting - Understand how salting cod is an example of osmosis. Cryometry - lowering the freezing point. Ebulliometry - increasing the boiling point of the solvent. Osmometry - and reverse osmosis Fun facts: Did you know that food takes longer to cook at higher altitudes? Find out why this happens and how to adjust recipes. The pressure cooker is not only a kitchen tool, but also a practical application of colligative properties to speed up food cooking. Charque meat is a traditional delicacy in many regions, especially in the Northeast of Brazil, and its preservation involves the application of interesting chemical principles. Salted cod is a classic example of how the concentration of solutes is related to the physical and organoleptic properties of food. Join us to explore these chemical concepts in a practical way and relate them to everyday situations. By understanding colligative properties, tonometry, cryometry, ebulliometry and osmometry, you will be better prepared to answer ENEM questions and will also appreciate the world around you in a completely new way. Don't miss this unique and interesting class!
