AP CHEMISTRY
Intermolecular Forces & Phase Changes
Visually compare London Dispersion, Dipole-Dipole, and Hydrogen Bonding. Manipulate kinetic thermal energy to watch how differences in IMF strength determine exact melting and boiling point thresholds.
AP CHEMISTRY
Phase Diagram Explorer
Interactive phase diagrams for H₂O and CO₂. Explore triple points, critical points, and supercritical fluid regions. Identify the phase at any T,P coordinate.
AP CHEMISTRY
Colligative Properties Calculator
Calculate boiling point elevation (ΔTb = iKbm) and freezing point depression (ΔTf = iKfm) with interactive sliders. Visualize the temperature range expansion of solutions versus pure solvent. Adjustable van't Hoff factor for electrolytes and osmotic pressure calculation.
