A stone displaces 10ml of water . It’s volume is?
Answers
Answer:
submerged object displaces a volume of liquid equal to the volume of the object.
One milliliter (1 mL) of water has a volume of 1 cubic centimeter (1cm3).
Different atoms have different sizes and masses.
Atoms on the periodic table are arranged in order according to the number of protons in the nucleus.
Even though an atom may be smaller than another atom, it might have more mass.
The mass of atoms, their size, and how they are arranged determine the density of a substance.
Density equals the mass of the object divided by its volume; D = m/v.
Objects with the same mass but different volume have different densities.
Summary
Students use the water displacement method to find the volume of different rods that all have the same mass. They calculate the density of each rod, and use the characteristic density of each material to identify all five rods. Then students consider the relationship between the mass, size, and arrangement of atoms to explain why different rods have different densities. Students will be briefly introduced to the periodic table.
Objective
Students will be able to explain that materials have characteristic densities because of the different mass, size, and arrangement of their atoms. Students will be able to use the volume displacement method to find the volume of an object.
