The density of water is approximately 1 gram/ cubic centimetre (1 g/cm3). Stellite alloys are a group of cobalt-chromium super-alloys consisting of complex carbides in an alloy matrix predominantly designed for high wear resistance and superior chemical and corrosion performance in hostile environments. Nitrous oxide is a naturally occurring gas that is colorless and non flammable. Specific gravity(relative density) = Density of the Mathematically, density is defined as mass divided by volume: = where is the density, m is the mass, and V is the volume. A box with more particles in it will be more dense than the same box with fewer particles. Due to the low toxicity and low reactivity of its component metals, in many applications, galinstan has replaced the toxic liquid mercury or the reactive NaK (sodiumpotassium alloy). Cupronickels have excellent resistance to corrosion caused by sea water. At each lab station, place four or five of each of the four items (marbles, Popsicle stick pieces, crayon pieces, pasta noodles), as well as all of the other lab supplies.
