What is the features of water?
Physical properties. O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour.
What are four characteristics of water?
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.
- Polarity. A water molecule is slightly charged on both ends.
- Cohesion. Hydrogen bonds hold water molecules together, as seen in the picture above.
- Adhesion.
- High Specific Heat.
What is the most unique feature of water?
How do you make drinking water safe and important?
In an emergency, water contaminated with germs can often be made safe to drink by boiling, adding disinfectants, or filtering. IMPORTANT: Water contaminated with fuel or toxic chemicals will not be made safe by boiling or disinfection.

Why is water important in schools?
Water Access in Schools. Providing access to drinking water gives students a healthy alternative to sugar-sweetened beverages. It helps to increase students’ overall water consumption, maintain hydration, and reduce energy intake if substituted for sugar-sweetened beverages.
What are the 5 characteristics of water?
Unique properties of water
- Water is polar.
- Water is an excellent solvent.
- Water has high heat capacity.
- Water has high heat of vaporization.
- Water has cohesive and adhesive properties.
- Water is less dense as a solid than as a liquid.
What are the uses of water in school?
Water is mostly used in schools for drinking and toiletry purpose. As an essential element for survival, water is considered to be the need of the day. It’s used for various purposes like drinking, cleaning, gardening, etc. In schools, we must ensure to protect this water by not wasting it too much.
What are the benefits of water?

What makes h2o unique?
In the liquid form, the hydrogen atoms of one water molecule are attracted to the oxygen atom of another molecule. Each water molecule can form up to four of these hydrogen bonds and, collectively, they give water a cohesiveness unique in liquids.
What makes water unique?
Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
What are the characteristics of pure water?
In its pure form, water is a colorless, odorless liquid that has a specific gravity, or density, of 1 gram per milliliter at 39.2 degrees Fahrenheit (4 degrees Celsius). If water is not pure, several of its properties change, including its freezing point,boiling point and conductivity.
What are the important characteristics of safe drinking water?
The state of drinking water supplies can be quantified by four important characteristics: quality, quantity, reliability, and cost.
Why is safe drinking water important in paragraph?
Clean water is essential not only to remain safe from disease but also to maintain good health. If the crops and grains are given contaminated water, the bacteria and disease will spread to those who consume the fresh produce. Therefore, water that is used for agriculture must also come from safe and clean resources.
What happens when oil is mixed with water?
So what happens when you try to mix oil and water? The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water.
