## Activity: Generalized Leibniz Notation

Static Fields 2023 (6 years)
This short small group activity introduces students to the Leibniz notation used for partial derivatives in thermodynamics; unlike standard Leibniz notation, this notation explicitly specifies constant variables. Students are guided in linking the variables from a contextless Leibniz-notation partial derivative to their proper variable categories.
What students learn
• Leibniz notation is learned or refreshed
• Explicit denotation of constant variables (the modified Leibniz notation used in thermodynamics is unique in this way)
• Media
1. In the middle column below, list each variable in the box connected to the description of the role of the variable.

2. If $a=c^3+7bc-5b^2$, find $\left(\frac{\partial a}{\partial b}\right)_c$
3. For the same equation, find $\left(\frac{\partial b}{\partial c}\right)_a$
