PPT-The idea of density

Taking up space Which is heavier a tonne of lead or a tonne of feathers Everyone knows that lead is heavier than feathers but that is not the right answer Tonne of anything weighs the same. 42 Calculation of the density of states in 1 2 and 3 dimensions We will here postulate that the density of electrons in space is constant and equals the physical length of the sample divided by 2 and that for each Principles Density The density pronounced rho of an object is the ratio of its mass to its volume Since very few substances have exactly the same density this property can be used to identify an element or compound Buoyant Force When you are swim during .
