Since ancient times it was harvested to provide clothing and is an important part in textile trade because of its insulation. Woolen fabric is when the woolen …

…an experimental error is he always took the temperatures in the same order. The difference in seconds could change the data by a degree. The experimenter could improve this by rotating or making the measuring order randomly. Other areas of study can be the effect of the amount of layers of insulation on how much heat is retained.
