Product Code : SCL-H-14592
Indian Lab Suppliers supplies the Newton's Law of Cooling Apparatus (Product ID: 14592) as part of its heat and thermal physics range. This apparatus records how a hot liquid cools so students can verify Newton's law of cooling.
Quick Answer
Newton’s law says the rate of cooling is proportional to the excess temperature over the surroundings, which holds well for small temperature differences. A copper or stainless-steel calorimeter of 200–500 ml sits in an outer jacket of Styrofoam, Bakelite or wood, with a wooden or copper stirrer and a stand. Temperature is read on a mercury or alcohol thermometer or a digital sensor over 0–100 °C, to ±0.5 °C, and plotted against time. Please confirm the calorimeter material, capacity and thermometer type at quotation. Handle hot water with care, and a mercury thermometer with extra care.
