Aims: Investigate and determine the specific heat or the rate of heating of variation between the continental and water properties on the earth. The study will help us understand the unequal cooling or heating of the dry land and water and their impact on the global climate.
Hypothesis: In order emphasize study this phenomena, I will be testing the following hypothesis:
Soil will have a higher rate of heating than water.
This hypothesis is based on the theory of thermodynamics and the concept of specific heat. The theory of thermodynamic is the field of science that includes the relationship between heat and other kinds of energy. The specific heat, also called the specific heat capacity, is a physical property of the matter. It is the quantity of heat required to raise the temperature of a unit of mass of a substance by one degree Celsius. Different substance have different specific heat because of the difference of their molecule structure. Take water as an example, because the structure of its molecule, it requires a much more amount of heat to raise one Celsius than the soil or many other substance in the earth. So, it has a higher specific heat than soil.
Very nice. Thank you. After countless web pages I bumped into your blog entry which very readably helped this dad help his 9th grader do/understand and not remain deflated by homework about:
ReplyDelete(Ahem...) the ratio of "difference in temp" (of a substance heated up) relative to ("per") grams (mass) of that substance
(Temp2 - Temp1) / #grams of stuff = change in temp "per" gram.
Then comparing that to the properties of another substance also being heated, and WALA using that information to see the situation at hand.
Initially I could not understand what it meant to calc "per gram" when there are more than one gram of the stuff. I needed a worksheet to show me that "per gram" meant "all the grams" just like MPH (Miles Per Hour) = M/H at an instant in time (the moment in time you look at your speedometer) as if it were for "all the hours" but this one moment is sufficient for now.
Temp Change Per Gram is like saying TPG (see MPH above except the grams is not like Hours in that the mass, unlike time, stays constant, whatever you had in the dish.
An instant of #grams" is not "one gram" but I was reading it that way and needed a different concept to make the jump from measuring Hours in MPH (or MpH) to measuring grams in Temp per Gram.
TaDah, I may be unschooled but if someone can lend their thoughts in such a blog, I can be of use to my 9th grader. Thank you Bruce Chi for that.
