|
Water retains more heat than other materials, allowing coastal regions to remain warmer in winter seasons.
|
|
|
Water absorbs heat when it freezes, helping it to insulate lakes and ponds from cold temperatures.
|
|
|
Water looses heat when it changes to a vapor, helping to keep animals cool through perspiration.

|
|
Water retains less heat than other materials, keeping aquatic ecosystems cooler than those on land.

Detailed explanation-1: -Which statement correctly describes one way that the properties of water affect heat and temperature? Water retains more heat than other materials, allowing coastal regions to remain warmer in winter seasons.
Detailed explanation-2: -Explanation: Among the following options Alpha (A) is correct because the specific heat capacity of water is very large and it can absorb large amount of heat before raising it’s temperature.
Detailed explanation-3: -Answer and Explanation: The four unique properties of water that make it unique are high specific heat, high polarity, adhesion cohesion, and a lower density as a solid. Water having a high specific heat allows it to absorb heat energy without a subsequent change in temperature.
Detailed explanation-4: -The high specific heat of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans. This same concept can be expanded to a world-wide scale.
