Density

• What is the equation for density?

  Density = mass/volume
• What is mass?


  how much matter an object has
• what is volume?


  how much space something takes up
• what does the density of an object depend on?


  the substance and the state of matter
• how do you measure the density of an irregular object?


  you use displacement to find out the objects volume
• how do you measure the density of a liquid?


  you use an electronic balance to measure the mass of the liquid
• What is a paralax error?


  Measurement error - not putting the measuring cylinder on a flat surface
• what is a zero error?


  Balance does not show zero even though there is nothing on it
• Volume of water displaced = .....?


  Volume of object
