|
Water has a high heat of vaporization. Since their hometown was hotter, it was probably more humid than at the beach.
|
|
|
Water has a high heat capacity. Since it takes a lot of energy for hydrogen bonds to break and for water to increase in temperature, the general temperature by the ocean is cooler than their hometown.
|
|
|
Water acts as a buffer. Water’s buffer properties influence the environmental temperature near large bodies of water, making the air cooler.
|
|
|
The covalent bonds within molecules of water are able to absorb a high amount of energy from the environment. This turns large bodies of water into heat sinks that result in milder environmental temperatures.

Detailed explanation-1: -Specific Heat: Water has a very high heat capacity. This means that it retains heat for a long time relative to the air. One important result of this is that large bodies of water moderate temperature. Coastal areas have less extreme summer and winter temperatures than the interior of major land masses.
Detailed explanation-2: -Cohesion allows for the development of surface tension, the capacity of a substance to withstand being ruptured when placed under tension or stress. This is also why water forms droplets when placed on a dry surface rather than being flattened out by gravity.
Detailed explanation-3: -Adhesion is the attraction of molecules of one kind for molecules of a different kind, and it can be quite strong for water, especially with other molecules bearing positive or negative charges.
Detailed explanation-4: -Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances).
