Charged and Neutral Atoms
Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

Seeing Specific Heat and Latent Heat
What happens inside a melting solid? Prospective physical chemists observe a solid-to-liquid phase change at the molecular level using an inspired interactive. Pupils add heat to a close system, then monitor changes in kinetic and...

Specific Heat and Latent Heat in Condensation
There's more to melting than meets the eye! Junior physical chemists investigate the differences between specific and latent heats as a substance undergoes a phase change. Users remove heat from the system and observe changes in kinetic...

Comparing Dipole-Dipole to London Dispersion
Which intermolecular force is the strongest? Scholars test the relative strength of London dispersion forces, dipole-dipole interactions, and induced dipoles using a simulator. The interactive allows learners to pull on paired molecules...
