The density of water is 1000kg/m3 and the density of ice is 900kg/m3. when 0.050 m3 of water is frozen, what will be the new volume (hint: the mass of the water will not change when frozen).

Sorry if this answer is a bit late...

We know that the volume of the water is 0.5 cube meters.

The density of water is 1.000 g/m^3 (that's the real density of water... maybe typos?)

The density of ice is 0.900 g/m^3 (that's the approximate density of ice)

First, let's multiply the volume of water by the density of the water to get the mass, since we know that the mass does not change with the ice gets frozen.

0.5 * 1.000 = 0.500 g

Now, let's divide that by the density of ice to get the volume of the ice.

0.500 / 0.900 = 5/9 cube meters

≈ 0.556 cube meters.

The volume of the ice is 5/9 or 0.556 cube meters.

Have an awesome day! :)

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
