Description
Prof. Marzena Dzida
We'll learn why something warm has a higher temperature than something cold. Why we constantly have to clean our room and it's always a mess. We all know the phase transitions from our daily experiences of boiling water or watching an ice-cream melt on a hot day. Thanks to this, we begin to understand that there are different phases of matter and that, under the right conditions, matter can change phase, in which its properties change in a distinct and easily visible way. In this brief introduction, we consider the similarities and dissimilarities between phase transitions, and in particular how they are identified despite their sometimes exotic and different nature. We will analyze the phase diagram of water, carbon dioxide, tin. We will find and explain phase transitions around us and related effects. We will answer the following questions: How does a pressure cooker work? Why do we feel cold when we get out of the shower? Why are we ice skating and why can we throw snowballs? How can you get decaffeinated coffee? How is "Smoke" made in horror movies? We will describe the eruption of a geyser and much more. We will learn that physical chemistry is useful in managing companies, i.e. there will be a few words about systems thinking.
