These properties sum up the docket confirming that we're dealing with the familiar composition of water. It has the chemical formula H2O and comes with a CAS number. The Pure Water Density Standard contains a standard density of 0.9982g/mL at 20u00b0C and 0.9970g/mL at 25u00b0C. Its effectiveness remains unquestioned both at 20u00b0C and 25u00b0C, making it suitable for a myriad of applications that operate within different temperature settings. Temperature Versatility: Temperature ranges do not limit its performance.Consistent Performance: Its certified properties contribute to consistent performance, assuring reliable measurements every time. ![]() Accurate Calibration: The product's design integrates an advanced technology that guarantees accurate and precise readings.High-quality Standard: Manufactured from high-purity water, the Pure Water Density Standard is the ideal reference material for your density measurements.This verifies that the material does not compromise, ticking all boxes of highest global standards, and making it traceable to international requirements. The Pure Water Density Standard is a top-of-the-line product, bearing the globally recognized UKAS ISO/IEC17025 and ISO Guide 34 certifications. With this product, your scientific experiments and manufacturing processes will always be on point, thanks to its guaranteed precision and accuracy. It's a certified reference material perfected for calibrating instruments that measure density, an essential tool for industries like pharmaceuticals, chemistry, and manufacturing. If accurate and reliable density measurements form an integral part of your operational requirements, look no further than the Pure Water Density Standard. At sea level water boils at 212☏ (100☌), while at 5,000 feet, water boils at 202.9☏ (94.9 ☌).Pure Water Density Standard: Certified Reference Material for Precise Density Measurements The higher the altitude, the lower the air pressure, the lower the boiling point of water, and thus, the longer time to hard-boil an egg. Surface tension is responsible for capillary action, which allows water (and its dissolved substances) to move through the roots of plants and through the tiny blood vessels in our bodies.Īir pressure affects the boiling point of water, which is why it takes longer to boil an egg at Denver, Colorado than at the beach. In other words, water is sticky and elastic, and tends to clump together in drops rather than spread out in a thin film, like rubbing alcohol. The high heat index of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans. This is why water is valuable to industries and in your car's radiator as a coolant. Water has a high heat index-it absorbs a lot of heat before it begins to get hot. Water becomes a conductor once it starts dissolving substances around it. Pure water, which you won't ever find in the natural environment, does not conduct electricity. Both cohesion and adhesion make water molecules very sticky! ![]() Water molecules are also adhesive in that they stick to other surfaces. Water is the most cohesive among the non-metallic liquids. The water molecule is highly cohesive- it is very sticky, meaning water molecules stick to each other. ![]() Pure water has a neutral pH of 7, which is neither acidic (less than 7) nor basic (greater than 7). This means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients. Water is called the " universal solvent" because it dissolves more substances than any other liquid.
