Specific heat is the amount of heat absorb or released by a substance to change the temperature to one degree Celsius. To determine the specific heat, we use the expression for the heat absorbed by the system. Heat gained or absorbed in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:
Heat = mC(T2-T1)
By substituting the given values, we can calculate for C which is the specific heat of the material.
2510 J = .158 kg ( 1000 g / 1 kg) (C) ( 61.0 - 32.0 °C)C = 0.5478 J / g °C
If the solution is brilliant re in alkalies and decolorized
by acids it’s the time to used phenolphthalein in analysis as an indicator. The
resulting solution is acidic, so you need an indicator that has a pH range that
includes pH values below 7.0, like methyl orange, methyl yellow If titrating a
strong acid and a weak base and it’s time to use as an indicator called bromophenol
blue .
Answer: 1 mole of water (H2O)
Answer : Option A) Deforestation.
Explanation : Factors related to deforestation can lead to desertification in presence of natural drought.
As natural drought hit area is an area which has low amount of water supply in the land. It is also called as below average precipitation land when drought area is deforested it will lead to desertification. As the plants in the drought area are the reason why their is at least low water is found, if these vegetation is deforested then it will lose its capacity to hold water and the land will be deserted.
