There is a boat with a load in the pool filled with water. Will the water level in the pool change if you throw overboard a load that: a) wooden b) a piece of ice, but it has not melted c) a piece of ice that has melted d) a strong bag of water e) iron block

Whether an object sinks or not depends on its density. The problem is a pool filled with water. The density of water is taken as a standard and is equal to 1.00 x 10 ^ 3 (one multiplied by ten to the third power) kg / m ^ 3 (kilogram divided by cubic meter or cubic meter).

If the density of substances is less than the density of water, then they will not drown, but will float and this will not affect the water level in the pool. If the density of substances is greater than the density of water, then they will drown and, according to Archimedes’ law, displace water equal to the volume of a body immersed in it.

1. If a wooden weight is thrown into the pool, the water will not rise, since the density of the tree is lower than the density of water. For example, the density of oak is 810 kg / m ^ 3, and the density of water is 0.1 x 10 ^ 3 = 1000 kg / m ^ 3.

810 <1000.

The tree will float on the surface of the water and will not displace water from the pool, the water level will not change, the water level will not change.

2. If you drop a piece of ice into the water, the water level in the pool will not rise, because the density of the ice is less than the density of the water. The density of ice is 900 kg / m ^ 3, and the density of water is 0.1 x 10 ^ 3 = 1000 kg / m ^ 3.

900 <1000

The ice will float on the surface of the water and will not displace water from the pool and the water level will not change.

3. If you drop a piece of ice that has melted into the water, the water level in the pool will rise, because the melted ice is water. And if the volume of melted ice, that is, water, is added to the volume of water in the pool, then the volume will increase.

4. If a strong bag filled with water is thrown into the pool, the water level in the pool will change. Because the water density in the pool and in the package is the same ..

5. If an iron block is thrown into the pool, the water level will rise. Because the density of iron is lower than the density of water and 7.8 x 10 ^ 3 kg / m ^ 3, and the density of water is 0.1 x 10 ^ 3 = 1000 kg / m ^ 3. This means that the metal block will sink and displace water equal to its volume.

a) no. b) no. c) yes. d) yes. e) yes.
