Question

The density of mercury is 1•36×10^4kgm^3 at 0°c.calculate it values at 100°c and at 22°c take 3 linear expansivity if mercury 180×10^6k^1

Answer 1

The density of mercury is 1•3×10^4kgm^3 at 0°c.calculate it values at 100°c and at 22°c take 3 linear expansivity if mercury 180×10^6k^1

Answer 2

linear expansivity cannot have units of just °K.
I expect it is units of m^3/°K or something like that.

if so, density is inversely proportional to temperature.
Thus to get the density at 100°C = 373°K, you want

1.36*10^4 * 273/373

Maybe one of the physicists here can confirm this conjecture.
