The primary focus of ergonomics is on workplace efficiency, specifically how to design and arrange workspaces and tasks to minimize strain, enhance safety, and improve productivity for individuals. Ergonomics seeks to create a harmonious interaction between people and their work environments, considering factors like human anatomy, physiology, and psychology. By optimizing these interactions, ergonomics aims to reduce the risk of injury and discomfort, ultimately increasing efficiency and effectiveness in the workplace. This is why the focus is on creating workspaces that accommodate the physical and cognitive needs of workers, thereby promoting well-being and enhancing overall performance.

The other options relate to specific scientific phenomena rather than the holistic approach associated with ergonomics. Atmospheric pressure, chemical reactions, and temperature measurement do not directly pertain to the considerations of human factors and workplace design that are central to the field of ergonomics.
