Use Newton's Law of Cooling to find the temperature of a substance as a function of timetin minutes that has spent cooling of this relationship is given by y=2+, where is the temperature of the medium surrounding the cooling
object, a is the difference between the initial temperature of the object and the surrounding temperature and kisa constant
related to the cooling object. Two samples of the substance were hested in a container of boiling water until their inte
Temperatures were both 100° C. The first sample will be cooled by being left out at a room temperature of 24 C and the
second sample of the substance will instead be cooled off in a refrigerator with an inside temperature of The value of
a will equal the difference between each sample's initial temperature and that sample's surrounding temperature and the
cooling constant of the substance is k=0.12
