As a resident in a coastal area, from my everyday observation, water (sea) has
higher specific heat capacity than that of sand. Specific heat capacity by its definition
from education.com, is about how much heat energy is needed raise the temperature of
a substance. The specific heat of water is the amount of heat needed to raise its
temperature a certain amount. One of water’s most significant properties is that it takes
a lot of heat to it to make it get hot. Precisely, water has to absorb 4184 Joules of heat
for the temperature of one kilogram of water to increase 1 degree celsius (°C). On the
other hand, the specific heat capacity of sand is 830 joule/kilogram (°C), which means it
takes 830 joules only to raise its temperature per kilogram to 1 degree Celsius (°C). Which
means that a 1 degree Celsius (°C) increase in water’s temperature, sand has an increase
of 5 degree Celsius (°C) in temperature.
Further, the good thing of living in a coastal area is its breezes. During summer, it
is nice to have fun at the beach because of its relaxing breeze. Breezes are an effect of
the difference in the specific heat or water and sand (Sthito, R., 2015). Because of the
great differences of their specific heat capacity, this implies that their temperatures has
great differences, too.
In a sea breeze, the wind will blow from sea to land. During the day, since water
has high specific heat capacity than the sand, it is cooler than the sand. Since the sea is
colder than the sand, it has high density than the sand, too. With the formula, PV=nRT,
d=m/V, this implies that high density substance will have high pressure and low densities
have low pressures. By the rule of convection, more dense substance will go down and
less dense substance will go up. Thus during the day, air flows from the high pressure
region over sea to the low pressure region over land.
At night, land breeze takes place. The role of sea and sand is reversed. Since it
takes much time to heat up the sea because of its high specific heat capacity, it also takes
much time to cool down, and while sand easily gets hot, they also get cold at a short
time. By the rule of convection, air from land will rise up and air from the sea goes down.
Water has low pressure and sand has high pressure. Thus, at night, air flows from high
pressure region over land to the low pressure region over sea.
That is why living in a coastal area is like a paradise, it seems like nature will find comfort
for you working together for you to have a relaxing moment.
