The evolution of hydrogen gas occurs when a piece of sodium metal is dropped into a calorimeter containing water because sodium loses electrons and is oxidized, whereas water is reduced.

Hydrogen gas is created when sodium metal reacts with water, and sodium hydroxide is also created. In this way, one electron is removed from the metal (Na), and an electron is added, turning water into hydrogen gas.

A calorimeter is a device that is used in calorimetry, which is the process of calculating the heat produced by chemical reactions, physical changes, and heat capacity. Among the most popular kinds are titration calorimeters, isothermal micro calorimeters, accelerated rate calorimeters, and differential scanning calorimeters.
