# Density Flashcards

What is density

The mass per unit volume

What is the equation for density

Density=mass/volume

What is density measured in

Kg/M cubed or e

How do you find the density of a liquid

Place the measuring cylinder on a balance then fill it with the liquid and measure the new mass the difference in masses is the mass of the liquid the volume can be read from the cylinder and the density using the eqaution

How do you find the density of a solid

Measure the mass of the solid by placing it on the balance if the solid is a regular shape measure its dimensions using a ruler or a measuring tool and then using mathematical formula to find the volume Solid is a regular shape and mercy in water and most of the volume of the water displaced this is the volume of a solid find the density using the equation

What is the density of water

1g/cm cubed

What is 1g/cmcubed in kg/M cubed

1000kg/M cubed

If the density of an object is greater than the density of water what will it do in water

Sink

The density of an object is equal to the density of water what will it do in water

Float

Is the density of an object is less than the density of water what will it do in water

Float upwards towards the surface

What is the force of the particle on the wall equal to

The rate of change of momentum
