Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.

Question

c) Suppose you have a 2 cm x 2 cm x 2 cm ice cube that is
frozen at a temperature of 0°C. How much energy input
would be required to melt it?
d) Suppose you are making yourself 0.50 liters of tea but its
temperature is 75°C, which is too hot for you to drink. In
order to cool its temperature, you immerse three ice cubes of

the same dimension as the one in part c) in your tea. If the
energy used to melt the ice came from the internal energy (i.e.
temperature) of the tea, what is the lowered temperature of
your tea?
e) Suppose you do not drink the all of the tea, and you leave
50 ml in the cup. How much energy would be required to fully
evaporate the remaining tea? If this energy came from the air
in a room surrounding the cup of tea, how would the air
temperature change, i.e. by what amount and as an increase
or decrease? Assume the room has dimensions of 5 m x 5 m x
3 m and the air average density is 1.2 kg/m³.
