In this demo, two circuits are constructed to enable comparison of the brightness of a light bulb placed in a circuit with one cell and the brightness of the same light bulb in a circuit with three cells connected in parallel. In Next Steps the potential differences of the two circuits are also compared.
Physical changes that involve liquids and aqueous solutions can be studied using a polystyrene calorimeter like the one shown in Figure 1. Such materials can be applied to practical thermochemical... read more
