Question

Which has more density 1kg of water or 10kg of water?

Answer 1

The `"densities"` are the SAME..........

Explanation:

`"Density"` is a so-called intensive property, whose magnitude does not depend on the size of the system. For a given temperature, thus `10*kg` of water has the same density as `1*kg` of water:

`"Density, "rho` `=` `"Mass"/"Volume"`

`rho_1=(10*kg)/(10*L)=1*kg*L^-1` or `1*g*cm^-3`

`rho_2=(1*kg)/(1*L)=1*kg*L^-1` or `1*g*cm^-3`

And thus `rho_1` and `rho_2` are manifestly the same.

On the other hand, there are the so-called extensive properties, mass, moles, volume, etc. whose magnitude depends on the number of particles in the system.
