Hydrogen: Properties, Thermodynamics and Electrochemistry Worksheet

This worksheet is designed to reinforce and consolidate the knowledge gained from the ‘Hydrogen: Properties, Thermodynamics and Electrochemistry’ presentation. Aimed at students aged 15–18, it provides a series of questions and activities exploring the key physical and chemical properties of hydrogen, its energy characteristics in gaseous and liquid forms, and the principles behind its use as a fuel.

Students apply their understanding of key thermodynamic and electrochemical concepts, including Hess’s Law, enthalpy changes, spontaneous and non-spontaneous reactions, and the role of electrolysers in splitting water to produce hydrogen and oxygen. The worksheet includes an answer section to support learning and check understanding, helping students consolidate their knowledge and connect the underlying scientific principles to hydrogen technologies and their role in a low-carbon energy future.
