A graduated cylinder contains 62 ml of water. When a small metal block is added to the water, the volume of the water increases to 65.5 ml. If the block is 26g, what is the density

7.43 g/mL

Explanation:

Step 1:

Data obtained from the question. This include:

Volume of water = 62 mL

Volume of (Metal + water) = 65.5 mL

Mass of metal = 26g

Density =?

Step 2:

Determination of the volume of the block.

From Archimedes' principle, we understood that an object will displace its own volume when completely immersed in a liquid. The volume of the metal block can be obtained as follow:

Volume of water = 62 mL

Volume of (Metal + water) = 65.5 mL

Volume of the matal = Volume of (Metal + water) - volume of water

Volume of the matal = 65.5 - 62

Volume of the matal = 3.5 mL

Step 3:

Determination of the density of the metal block. This is illustrated below:

The density of an object is simply the mass of the object per unit volume of the object. It represented mathematically as:

Density = Mass /volume

Mass of the metal = 26g

Volume of the metal = 3.5 mL

Density =?

Density = Mass /volume

Density = 26g / 3.5mL

Density = 7.43 g/mL

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
