Density Flashcards
1
Q
State the equation for density. Give
appropriate units.
A
density (kg/m³) = mass (kg) ÷ volume (m³)
ρ = m/v
2
Q
Describe a method to determine
the density of a liquid.
A
- Place an empty beaker on top of a balance and zero the device
- Pour liquid into the beaker to determine the mass
- Pour the same liquid into a measuring cylinder and read off the volume
- Use ρ = m/v to calculate density

Q
When do objects float in water?
A
When the object is less dense than the
water displaced by it.
