What is the viscosity of water at 20 degrees Celsius?
The viscosity of water at a temperature of 20 degrees Celsius is roughly equal to 0.01 poise or 10-3 Pa. s (Pascal seconds). Alternately, this value can be represented as 1.0016 mPa.
What is the water density at 20 C?
UKAS ISO/IEC17025 and ISO Guide 34 certified, density: 0.9982 g/mL at 20 °C, density: 0.9970 g/mL at 25 °C.
What are 5 physical properties of water?
Physical properties of water are related to the appearance of water, namely, the color, temperature, turbidity, taste, and odor.
What are the main physical properties of water?
Introduction to Properties of Water
Water molecules form hydrogen bonds and are extremely polar. The five main properties of water are its high polarity, high specific heat, high heat of vaporization, low density as a solid, and attraction to other polar molecules.
What is the density and viscosity of water?
For example, the kinematic viscosity and density of water at 78 °C is around 0.37344 mm2 per second and 0.973 grams per cm3, respectively.
What makes water viscous?
Water has very strong intermolecular forces, hence the low vapor pressure, but it’s even lower compared to larger molecules with low vapor pressures. Viscosity is the property of fluid having high resistance to flow.
What temperature does water boil?
212°F (100°C)Water / Boiling point
Which temperature water density is high?
The density of water is maximum at 4 °C because, at this temperature, two opposing effects are in balance.

What are the 10 main properties 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.
Does water viscosity change with temperature?
For a given diameter, the relative viscosity of water inside the SWCNTs increases with increasing temperature.
Does water have high viscosity?
Water has a low viscosity due to the low inter-molecular bonds.
What are the 7 characteristics of water?
What are the four unique properties of water?
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.
At what temperature does water burn skin?
Most adults will suffer third-degree burns if exposed to 150 degree water for two seconds. Burns will also occur with a six-second exposure to 140 degree water or with a thirty second exposure to 130 degree water. Even if the temperature is 120 degrees, a five minute exposure could result in third-degree burns.
At what temp does water freeze?
32°F (0°C)Water / Melting point
Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes. It can be melted down to use as drinking water.
At what temperature water has maximum volume?
Water has maximum volume at 4-degree Celsius and maximum density at 4-degree Celsius. But when water is cooled down further its volume starts increasing and hence, the density of water decreases when cooled further below than 4-degree celsius.
Why is colder water more dense?
Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. Hot water is less dense and will float on room-temperature water.
What are the six properties of water?
The properties of water include cohesion, adhesion, capillary action, surface tension, the ability to dissolve many substances, and high specific heat.
What are the 12 properties of water?
Is hot or cold water more viscous?
Scientists have long known that cold water is more viscous than hot water, because the molecules are wiggling less rapidly, so they are effectively stickier.
Does water temperature affect surface tension?
In general, surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity.
What are the 4 major properties of water?
How hot of water can a human stand?
Children and older people, who typically have thinner skin, suffer more severe burns in a shorter time and at lower temperatures than adults. A child can suffer a third-degree burn in 124°F water in less than three minutes. Children and adults can be burned this badly in two seconds or sooner in 149°F water.
What is the highest temperature a human can survive?
How does – or doesn’t – your body cope in extreme situations? The maximum body temperature a human can survive is 108.14°F. At higher temperatures the body turns into scrambled eggs: proteins are denatured and the brain gets damaged irreparably. Cold water draws out body heat.
