First, we have to know that the formula of density is: As formula shown, density is total mass of the object divided by total volume of object, which means: 1 gram per cubic centimetre or 1 kilogram per cubic metre.Density of water is1 gram per cubic centimeter (1 g/cm3), but actually, the exact density of water is not really 1 g/cm3, but rather a bit less (very, very little less) than 1, so we can say thatgenerally the weight and volume of water is the same.What's the meaning of "Specific Gravity"?Specific Gravity means specific value of an object undernormal temperature and pressure. Polyamide Blood normally has a specific gravity of ~1.060. 0000172297 00000 n 0000042285 00000 n 0000137613 00000 n | Contact, Home ), Copyright 2000 - can be special ordered. Total elongation at failure of some polymers: Tensile modulus or Young's Modulus is the ratio of stress to strain within the elastic region of the stress-strain curve before the yield point. WebSpecific gravity is the (unit less) ratio of the solid wood density to the density of water at the same temperature. The best-known plastics of this group are polycarbonates(PC) used to build strong,toughproducts.
