In Florida daytime and nighttime temperatures usually only different by 5°C while temperatures in the desert often differ by as much is 40°CWhat role does water play in keeping temperatures in Florida from fluctuating Dramatically

To answer this question, we need to understand the concept of "specific heat" for water with respect to other compounds. According to the definition, specific heat of any substance is the amount of heat required to raise the temperature of that substance (per unit mass) by one degree Celsius (Q = c. m.ΔT).

It has been scientifically proven that the specific heat of water is higher than any other substance. This means that if the water is present in any environment, it will have the capacity to absorb more heat as compared to the area where no water is present. Further, water absorb heat during hot climate and then releases back during cold climate. This is the reason that, in Florida, where water is present, fluctuation in the temperature are only 5 degrees Celsius. On the other hand, in the desert, no water is present and thus fluctuations in temperature are high and can be directly linked to the presence and absence of sunlight during day and night along with other environmental parameters.
