Which of the following is typically part of the knowledge base of research and development scientists working on heating devices? (1 point)
O engineering rules and principles
marketing strategies
O substances and their properties
O sales projections
The correct answer is "substances and their properties". To arrive at this answer, we need to understand the role of research and development scientists working on heating devices.
Research and development scientists in this field are responsible for designing and improving heating devices, such as heaters or furnaces. In order to do this effectively, they need a deep understanding of the substances used in these devices and their properties.
For example, they may need to know the thermal conductivity of different materials to determine which one is the most efficient for transferring heat. They may also need to know the melting point or flammability of certain substances to ensure the safety of the heating device.
On the other hand, engineering rules and principles are also important for research and development scientists. These principles enable them to apply scientific knowledge to design and develop efficient and effective heating devices.
Meanwhile, marketing strategies and sales projections are not typically part of the knowledge base of research and development scientists. These areas are more related to the business and commercial aspects of the heating device industry, rather than the technical and scientific knowledge required for research and development.
Therefore, the correct answer is "substances and their properties".
The following option is typically part of the knowledge base of research and development scientists working on heating devices:
- Substances and their properties
