Construction PhysicsLaajuus (3 ECTS)

Objective

The course will provide the engineering student with the necessary basic knowledge of thermal physics, moisture and moisture diffusion. The student will understand that physical theories are models, based on observations and experimental measurements, describing the real world of engineering applications. The student will be able to classify natural phenomena and be familiar with the physical laws describing them, their basis and limitations. The student will understand the grounds of the practical applications of physics.
