Which condition did you change?
Labs / Chemistry
Calorimetry
Drop a hot substance and a cold one into the same insulated cup. Heat drains from the warmer side into the cooler side until both sit at one shared temperature. Drag a chamber up or down, or nudge the sliders, and the readouts predict the equilibrium temperature and the total heat that moved using q = mcΔT with energy conserved.

Why it matters
Why explore this?
Chemistry connects events too small to see with changes we can measure. This model helps you link particles, energy, and conditions to an observable result.

Questions to test
Predict first, try it in the model, then use what you observe to answer.
What to try
- The equilibrium temperature usually lands nearer one substance than the other. Which one, and what makes it "win"?
- Water has a huge specific heat. Swap iron for copper or lead — does a lower c pull the final temperature toward the metal or toward the water?
- Double the mass of the cold substance. Does that shift the final temperature as much as doubling its specific heat would?
- Can you choose masses and temperatures so the two substances meet exactly in the middle?
- Heat lost by the hot side equals heat gained by the cold side — so why don't their temperature changes match in size?
Explain
Make sense of what happened
Describe what happened at the particle or energy level, then connect it to the result you saw. A strong explanation names both the cause and the evidence.

What observation supports your explanation?
If you can answer all three using evidence from the model, you understand the main idea. If not, return to Explore and change one setting at a time.
