|
Water has special adhesive and cohesive properties.

|
Water has a very low heat capacity.
|
Explanation:
Detailed explanation-1: -Water has a high specific heat capacity-it absorbs a lot of heat before it begins to get hot.
Detailed explanation-2: -Covalent bonds give water a low heat capacity.
Detailed explanation-3: -Water has a very high specific heat. That means it needs to absorb a lot of energy before its temperature changes. Sand and asphalt, on the other hand, have lower specific heats. This means that their temperatures change more quickly.
Detailed explanation-4: -Water has a specific heat capacity of 4.186 J/g°C, meaning that it requires 4.186 J of energy (1 calorie) to heat a gram by one degree. Specific heat capacity is the amount of heat needed to raise one gram of a material by one degree celsius (oC).
