If this is an introductory activity, then it is really not important that students understand the details of specific heat capacity at this point! It is just important that students understand that different materials heat up and cool down at different rates; this has important implications for life on Earth. A material's specific heat capacity is the amount of heat (or energy) required to increase the temperature of one kilogram of the material by 1Â°C.
Mechanical Drawing Symbols. Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, and air conditioning. It is a powerful tool that helps analyze complex systems. These drawings are often a set of detailed drawings used for construction projects; it is a requirement for all HVAC work.
Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing. This list includes abbreviations common to the vocabulary of people who work with engineering drawings in the manufacture and inspection of parts and assemblies. Technical standards exist to provide glossaries of abbreviations, acronyms, and symbols that may be found on engineering drawings. Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, ASME standard Y14.38 is probably the most widely used.
