In this webinar, we will review the two main diagrams of phase changes and thermodynamics.  These are phase diagrams (solid, liquid, gas) and heating curves.  Phase diagrams can give us useful info about densities, boiling and melting curves, and can also help explain colligative properties.  Heating curves show quantitatively how phases can change.  We use heating curves in calorimetry.

At a glance


Essential skills

  • Read a phase diagram

  • Read and calculate with a heating/cooling curve

  • Visualize colligative properties on phase diagrams through freezing point depression and boiling point elevation


Knowledge Fundamentals

  • Fundamental phases of matter

  • Phase diagrams

  • Phase transitions

  • Heating and cooling curves

  • Connection between phases and colligative properties


On the MCAT

  • The test knows that you have studied basic phase diagrams, so the test will complicate these diagrams for you. Remember to apply the same basic principles!

  • Phases have overlaps with colligative properties and heating/cooling curves, both of which can be calculation heavy


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
