Premium practical diagram for calibration curve of a thermometer.
Why this practical matters
These experiments show how energy moves into or out of a substance and changes its temperature or state.
Use the ice point and steam point to turn a raw thermometer reading into a real temperature.
What You Need
Apparatus
- thermometer
- calorimeter or beaker
- heater or hot water/steam setup
- balance, stirrer, and insulation
- standard laboratory thermometer
Key Formula
temperature scale = straight-line calibration between fixed points
Say the formula out loud before you start the calculation. It helps students and examiners follow your logic.
How To Do It
- Set up the calibration curve of a thermometer apparatus neatly and make sure the scale or meter reading starts from a known point.
- Reduce heat loss where possible, stir for even temperature, and record the start and finish values clearly before doing the calculation.
- Use the result to explain the physics idea in simple English. Use the ice point and steam point to turn a raw thermometer reading into a real temperature.
Simple Explanation
Use the ice point and steam point to turn a raw thermometer reading into a real temperature.
In the lab, we are not just collecting numbers. We are showing a physics rule in a real and reliable way. That is why careful setup, repeat readings, and clear labelling matter so much.
Common Mistakes
- Letting the thermometer touch the container.
- Not stirring the liquid.
- Using wet ice when dry ice is needed.
Exam Tips
- Mention insulation and lids in exam answers.
- Explain why a steady final temperature matters.
- State the energy balance in words and in symbols.
- State the observation, the method, and the conclusion in that order.
