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: -Special properties of water are its high heat capacity and heat of vaporization, its ability to dissolve polar molecules, its cohesive and adhesive properties, and its dissociation into ions that leads to the generation of pH.
Detailed explanation-3: -Physical properties of water are related to the appearance of water, namely, the color, temperature, turbidity, taste, and odor.
Detailed explanation-4: -And so the main point here is that water has a high heat of vaporization, meaning it takes a large amount of energy to convert 1 g of liquid water into gaseous state.
