Course description and aims

Geochemistry is a field of study that uses "chemistry" to explore the formation and evolution of the Solar System, the structure and evolution of materials in the Earth's interior, and the origin and evolution of the Earth's surface environment including the atmosphere, hydrosphere, and life. In the first half of this lecture (Class 1 to 7), the structure and properties of atom, which is the smallest unit of matter, will be introduced, and the diversity of terrestrial materials created by the different properties of each element will be explained. The second half of the lecture (Class 8 to 14) focuses on thermodynamics, an important physical and chemical law governing the formation of terrestrial and planetary materials, and lectures on its basic concepts, free energy, and so on. In this way, this course aims to approach terrestrial and planetary materials from both microscopic (atomic) and macroscopic (thermodynamic) perspectives.

Student learning outcomes

The course aims to provide students with the basic knowledge of geochemistry necessary for studying Earth and Planetary Science. In the first half of the course, students will learn the structure of atoms, the smallest unit of all matter, and the properties of the elements that result from the structure of atoms. In the second half of the course, students will learn the first and second laws governing thermodynamics, various thermodynamic functions, free energy and phase equilibrium.

Keywords

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
