Question

what are four properties of water?the polarity of water molecules affects the properties of water.this is because waters polarity affects how water moleculesinteract with one another and with other types of molecules.it sticks to itselfthe property that holds molecules of a substancetogether is cohesion. water molecules sticktogether tightly because of their polarity, so waterhas high cohesion. because of cohesion, waterforms droplets. and water poured gently into aglass can fill it above the rim because cohesionholds the water molecules together. some insectscan walk on still water because their weight doesnot break the cohesion of the water molecules.it sticks to other substancesthe property that holds molecules of differentsubstances together is adhesion. polar substancesother than water can attract water moleculesmore strongly than water molecules attract eachother. these substances are called \wettable\because water adheres, or sticks, to them sotightly. paper towels, for example, are wettable.water drops roll off unwettable, or \waterproof,\surfaces, which are made of non-polar molecules.cohesion: __________adhesion: ________four main properties of water.1. ________2. ________3. ________a. specific heat4. __________a. solvent

Explanation:

1. Cohesion: Defined as the property that holds identical water molecules together tightly due to polarity, enabling phenomena like water droplets, water rising above a glass rim, and insects walking on water.
2. Adhesion: Defined as the property that holds water molecules to molecules of other polar (wettable) substances more strongly than water attracts itself, while water rolls off non-polar (unwettable) surfaces.
3. Four Main Properties:

• Cohesion is a core property from the text.
• Adhesion is another core property from the text.
• High specific heat is listed as a sub-point, so it is a main property.
• Acting as a solvent is listed as a sub-point, so it is a main property.

Answer:

Cohesion: The property that holds water molecules together tightly due to their polarity, allowing water to form droplets, fill above a glass rim, and support insects on its surface.
Adhesion: The property that makes water stick tightly to other polar (wettable) substances, while rolling off non-polar (unwettable) surfaces.
Four Main properties of water:

1. Cohesion
2. Adhesion
3. High specific heat
4. Ability to act as a solvent
