Q = m*s*dT, where Q = heat, m = mass, s = specific heat, and dT is the change in temperature (T2 - T1). You can use this formula to calculate the specific heat. In the case of gases, just replace the mass by moles of the gas.
eXtensible markup language. XML is a file extension for an Extensible Markup Language (XML) file format used to create common information formats and share both the format and the data on the World Wide Web, intranets, and elsewhere using standard ASCII text. XML is similar to HTML.
In other words, it is used to markup or describe data. To achieve this description of data, XML relies on Document Type Definition (DTD). You could say that this is the âmachineâsâ dictionary, which allows it to understand the markup language.
