Density. The mass per unit of volume of a substance. The mass per unit of volume of a substance. Basically this means…. How heavy something is compared to its size. Tools to Measure Density. Measure mass of object using a balance . Measure volume of object using a graduated cylinder .
The mass per unit of volume of a substance.
How heavy something iscompared toits size.
… a combination of the mass unit “g” and the volume unit “cm3” or “mL”.
This increases the volume of the boat without increasing the mass by much.
If it’s density is less than 1g/mL it floats toward the surface.
If it’s density is equal to 1g/mL it remains suspended in the water.How about a submarine? Sometimes it sinks and sometimes it floats.
The average density of a boat -- the combination of the steel and the air -- is very light compared to the average density of water. So, very little of the boat actually has to submerge into the water before it has displaced the weight of the boat.
