Is the value of specific heat capacity of aluminium higher or lower than the standard value? Why?
Aluminum Specific Heat Capacity
This is not my expertise. As I have been researching this the past hour to re-educate myself, no one else has answered you. So, I will attempt to get you in the right direction by what I found. I found two specific heat values for Aluminum. The recent one is from wikipedia with the other an old text someone quoted. The specific heat of aluminum, cAl, is 0.897J g?1 K?1; this is, 0.214cal g?1 °C?1. [per wikipedia] AND The specific heat capacity of aluminum as 0.215 kcal/(kg C) [The Handbook of Chemistry and Physics, p. D-217, 1979]. Standard Value was the harder item. I found it is referred to as Hro [Where the o is a circle]. I could only find it referring to water. To measure heat for each metal, it was always compared to the heating water, which is used as the standard. I'm guessing its like a thermometer filled with mercury. The mercury gets heated and the lines are marked to tell you how hot the air is. Hope that helps... Maybe someone else will jump in...
Specific Heat Capacity Of Aluminum
RE: Specific heat capacity of aluminium...? Is the value of specific heat capacity of aluminium higher or lower than the standard value? Why?
Wait! Let s think here. Aluminum has a relatively high index when it comes to most foods. For example, if you put some fries on a piece of aluminum and heat it up, the fries will become hot much faster than the aluminum. Consider this: The iron cover of a manhole. It will have a lower specific heat capacity than a puddle of water. It takes longer for the water to absorb the same amount of heat energy. If one touches a manhole iron cover on a hot day, it will burn him or her. However, a puddle of water, with the same surrounding temperature will remain relatively cool. Specific Heat Capacity = Calories/( grams X degrees celsius)
