a cold body of water located between north America and eastern Russia IS
The boundary between a cold and warm air mass is called a front. One type of air will replace another as a front passes.
The boundry between the surface water and deep water. *boundary We know that warm water stays atop cold water. In fact, the change in temperature is abrupt, not gradual. The warm water layer is almost uniform in temperature. So is the cold water layer below. The dividing interface---pycnoline---is where the temperature changes from warm to cold.
Our body temperature is high then cold water so when it comes in contact with our body energy in the form of heat is transferred from body to water so it decreases our body temperature and we feel cold.
A sharp change in temperature or air mass characteristics is considered a boundary between two different fronts. This boundary is known as a "frontal boundary" and often leads to distinct weather changes and patterns.
both warm and cold front
Because, when you have been swimming, you have been in the water, and water is sometimes cold, so when the cold has entered your body, your body goes cold.
True.
One theory is that the cold water causes the blood vessels surrounding stomach to shrink, slowing absorption. The body also has to expend energy to heat cold water to body temperature (hydrating the body more quickly). On the other hand, after physical exertion, cold water may help cool the body more effectively than room temperature water. Note: the Difference between the two are minute and for the most part negligible. the body uses few calories in order to raise the temp of water, and it does so quickly.
well chilled water temperature is below 40C but higher than 00C. where as cold water which we get from cooling tower is usually about 200C to 360C but below our body temperature.
