Unit Overview
In this unit, we explore the powerful relationship between heat, energy, and work. Starting from the microscopic motion of particles (**kinetic theory**), we scale up to the laws that govern the entire universe. We'll investigate how energy flows, why it spreads out (**entropy**), and how we harness it to power the modern world through **heat engines**. From melting ice to car engines, thermodynamics explains the rules of energy transfer.
Essential Questions
- โน What is the difference between "hot" and "heat"?
- โน Why does heat always flow from hot to cold?
- โน Can we ever build a 100% efficient machine?
- โน How does the motion of invisible particles create the pressure we feel?
