Newton's Law of Cooling Apparatus
Product Code : SCL-PLE-11750
Quick Answer: The Newton’s Law of Cooling Apparatus places a polished metal vessel inside a double-walled water jacket, with a lid that takes two thermometers, one for the hot liquid and one for the surroundings. Readings over time show how the rate of cooling depends on the temperature difference.

Key Features
- Double-walled water jacket keeps the surroundings at a steady temperature.
- Lid drilled for two thermometers: body and ambient.
- Mechanical stirrer supplied to keep the liquid temperature uniform.
- Removable insulating cover with low-conduction ports.
Technical Specifications
| Specification | Value |
|---|---|
| Inner vessel | Polished, high-conductivity metal |
| Enclosure | Double-walled water jacket |
| Thermometer ports | Two (body and ambient) |
| Stirrer | Mechanical stirrer included |
| Lid | Removable insulating cover |
How It Is Used
With this Newton law of cooling apparatus, hot liquid is poured into the inner vessel, the jacket is filled with water, and both thermometers are read at regular intervals while the liquid is stirred. A graph of temperature against time gives the cooling curve, and comparing the rate of cooling with the temperature excess over the jacket shows the exponential nature of cooling.
Frequently Asked Questions
Why does the Newton’s Law of Cooling Apparatus have a water jacket?
The double-walled water jacket holds the surroundings at a steady temperature, so the cooling of the liquid can be measured against a stable ambient reading on the second thermometer.
Is a stirrer included with the Newton’s Law of Cooling Apparatus?
Yes. A mechanical stirrer is included to keep the liquid at a uniform temperature.
