High specific heat example
WebWater has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius. For water, this amount is one calorie, or 4.184 Joules. As a result, it takes water a long time to heat and a long time to cool. WebJun 26, 2024 · The sample selected is a polypropylene (PP) with magnesium hydroxide at 30 wt.%.
