You Be The Chemist Section 2 Density

The amount of matter per volume (how much matter occupies a given space)

• Length

• Density

• Volume

• Weight

The formula for density is

• Length x width

• Length x width x height

• Mass / volume

Density can change with temperature

• True

• False

How does temperature affect density

• As the temp increases, the particles speed up and become MORE dense

• As the temp increases, the particles speed up and become LESS dense

• As temp increases, the particles slow down and become MORE dense

• As temp increases, the particles slow down and become LESS dense

To find the density of a liquid the first step is

• Pour liquid into a graduated cylinder and find the volume

• Find the mass of the liquid by subtracting the mass of the empty graduated cylinder from the mass of the filled graduated cylinder

• Find the mass of the filled graduated cylinder

• Find the mass of the empty graduated cylinder

• Use the formula Density = Mass / Volume

To find the density of a liquid the second step is

• Pour liquid into a graduated cylinder and find the volume

• Find the mass of the liquid by subtracting the mass of the empty graduated cylinder from the mass of the filled graduated cylinder

• Find the mass of the filled graduated cylinder

• Find the mass of the empty graduated cylinder

• Use the formula Density = Mass / Volume

To find the density of a liquid the third step is

• Pour liquid into a graduated cylinder and find the volume

• Find the mass of the liquid by subtracting the mass of the empty graduated cylinder from the mass of the filled graduated cylinder

• Find the mass of the filled graduated cylinder

• Find the mass of the empty graduated cylinder

• Use the formula Density = Mass / Volume

To find the density of a liquid the fourth step is

• Pour liquid into a graduated cylinder and find the volume

• Find the mass of the liquid by subtracting the mass of the empty graduated cylinder from the mass of the filled graduated cylinder

• Find the mass of the filled graduated cylinder

• Find the mass of the empty graduated cylinder

• Use the formula Density = Mass / Volume

To find the density of a liquid the fifth and last step is

• Pour liquid into a graduated cylinder and find the volume

• Find the mass of the liquid by subtracting the mass of the empty graduated cylinder from the mass of the filled graduated cylinder

• Find the mass of the filled graduated cylinder

• Find the mass of the empty graduated cylinder

• Use the formula Density = Mass / Volume

To find the volume of a regular solid, the first step is

• Use the formula Density = Mass / Volume

• Find the mass of the solid

• Find the volume of the solid using the formula volume = length x width x height
