Interpretation:
The reason due to which 1 g of water needs more energy to raise the temperature as compared to 1 g of aluminium needs to be explained.
Concept Introduction :
The specific heat capacity is the amount of energy that should be added to one unit of mass of the substance in order to increase the temperature by one unit.

Answer to Problem 2E
Because water has more specific heat than aluminum.
Explanation of Solution
The specific heat of aluminum is 0.900J/goC and the specific heat of water 4.186 joule/g oC.
The amount of heat required for temperature change can be calculated as follows:
So, it directly depends on the specific heat capacity of the substance.
Due to the lower value of specific heat of aluminum than water, water require more energy to raise the temperature.

- b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.
