5.2 Plenary Answer
5.2 Plenary Answer 04 October 2011 14:16
· If you take a piece of wood that's got a density of 2.4g/cm3 and cut it exactly in half, what will the density of each of the 2 new pieces of wood be?
· 2.4g/cm3!
· You've halved the mass of each block but you've also halved the volume of each block, so the ratio m/V remains contant!
· For example…
· ρbig block = m/V = 240/100 = 2.4g/cm3
· ρsmall block = m/V = 120/50 = 2.4g/cm3
· If you take a piece of wood that's got a density of 2.4g/cm3 and cut it exactly in half, what will the density of each of the 2 new pieces of wood be?
· 2.4g/cm3!
· You've halved the mass of each block but you've also halved the volume of each block, so the ratio m/V remains contant!
· For example…
· ρbig block = m/V = 240/100 = 2.4g/cm3
· ρsmall block = m/V = 120/50 = 2.4g/cm3
5.2
· 5.2 recall and use the relationship between density, mass and volume:
density = mass / volume ρ = m / V
