![]() Archimedes principle is a law of physics fundamental to fluid mechanics.It was formulated by Archimedes of Syracuse. The refractive index of normal ice is 1.31 (from List of refractive indices).In general, an index of refraction is a complex number with real and imaginary parts, where the latter indicates the strength of absorption loss at a particular wavelength. Archimedes principle (also spelled Archimedess principle) states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. That's why the difference between heat of vaporization at 25C (energy required to break all H-bonds between 1 gram of initially slow moving molecules) and at 100C (energy to break all H-bonds of 1 gram of fast molecules) is LESS then the energy required to make all of those 1 gram of molecules faster. The refractive index of water at 20 ☌ for visible light is 1.33. It is temperature-dependent, but this relation is said to be non-linear, and also, it is unimodal in nature rather than monotonic. ![]() And as more molecules fly off, less energy is needed to break off the remaining bonds. The density of water is approximately 1 gram/ cubic centimetre (1 g/cm 3). Then, plug these values into the formula and perform the division to find the density. It occurs more and more as you near towards it. To calculate the density of water, you use the formula: Density () Mass (m) / Volume (v) Measure the mass of the water sample using a scale and the volume using a graduated cylinder or similar tool. You don't need to wait until 100 degrees for vaporization to begin. Remember that when you apply energy to water, some of it will increase the avg kinetic energy of the molecules (related to the temperature) and some will be spent to break off all hydrogen bonding and send the molecules flying away (related to heat of vaporization at a GIVEN temperature). This widget calculates the density of water at various temperatures and pressures. The density of pure water is 1gm/cm3 or 1000kg/m3. ![]() How come only 40 calories can increase the water temperature by 75 degrees to its boiling point, if the specific heat property tells us that 40 calories can only increase it by 40 degrees? Formula: H 2 O Molecular weight: 18.0153 IUPAC Standard InChI: InChI1S/H2O/h1H2 Copy. ![]()
