a 2-g block of an unknown substance is placed in a container of water. it displaces 2.5 cm(cubed) of water. will the block sink or float? explain...
thanks!1

for this problem, you have to look at the density of the substance versus the density of water.
Density=mass/volume
So for this object, you take into account the mass and the amount of water it displaces (aka volume)
density=2grams/2.5mL water
density= 0.8 g/mL
The density of water at room temperature is about 1.00 g/mL
Since the density of the object is less than the density of water at room temperature, the object will float.
Hope that helps!

it all depends on the density of the block. If the density of the block is higher than water it'll sink, but if water's density is higher then it'll float!

If it's so easy, perhaps you should do your own homework
