Warming water up from 4o will decrease its density and so will cooling it (until it freezes).
Using this renewed equation, we can see that density and temperature are indirectly proportional; as T increases, d decreases, as T decreases, d increases.Use this equation!
In general, density decreases as temperature increases. However, water is strange in that it expands when it freezes, so water is most dense at 4oC. Warming water up from 4o will decrease its density and so will cooling it (until it freezes).

I was thinking of gases. You are using water in its liquid form. You can't use this equation with liquid water!
