TO STUDY THE RELATION BETWEEN TEMPERATURE OF A HOT BODY AND TIME BY PLOTTING A COOLING CURVE.

APPARATUS WE SUPPLIED WITH THIS EXPERIMENT NEWTON'S LAW OF COOLING APPARATUS TWO THERMOMETERS STOP WATCH OPTIONAL ACCESSORIES WITH THIS EXPERIMENT 1.HEATING ARRANGEMENTS (HEATING PLATE ) 2. ELECTRONIC BALANCE According to Newton's law of cooling, the rate at which a hot body lose heat is directly proportional to the temperature difference between hot body and surrounding provided the temperature difference is small. Core Principles Proportional Cooling: The hotter an object is compared to the room, the faster it loses heat. As it cools and gets closer to room temperature, the cooling process slows down. Convective Dominance: The theory primarily simplifies convective and conductive heat transfer into a linear mathematical relationship. Small Temperature Differences: It functions best and remains accurate only when the temperature difference between the object and the environment is relatively small.
