Trace Pressure is a “thermodynamic” variable along with Trace Temperature and Trace Volume. The fourth variable, the number of non-Silent Messages, N, is obvious. In the following diagram, two parts of the trace have approximately the same volume but different “temperature” that result in approx. same “pressure” according to a metaphor of an ideal gas law:

Trace Temperature is an external quantitative (a number) or qualitative (for example, “hot”, “warm”, or “cold”) trace attribute of a trace or log or its fragment such as Activity Region that measures importance of the incident:
It is one example of Trace Field. Being an external attribute, independent from content, the trace with very few or no messages (Sparse Trace) can still have very high “temperature.” However, this analysis pattern is not the same as News Value which is an internal attribute based on trace content that measures its importance.

Trace Volume counts not only messages but also Silent Messages:
The volume metaphor can also be applied to parts of the trace such as Activity Regions, Threads (and Adjoint Threads) of Activity, and various braids.
