- 1Densitymass/volume
- 2Describe experiments to determine density using direct measurements of mass and volumeFor a regular solid
Measure the width, height and depth of the block in cm with a half metre rule.
Volume = width x height x depth
Find the mass of the block in grams using an electronic balance.
Use the formula to calculate density. - 3Describe experiments to determine density using direct measurements of mass and volumeFor a liquid
find the mass of a dry clean measuring cylinder. pour in the liquid and find the new mass. find the mass of the liquid using m = m2 - m1 grams. alternatively place the dry measuring cylinder on the balance and zero the balance so you can read off the mass of liquid directly when you reweigh the cylinder.
volume = width x height x depth
your measuirng cylinder may be calibrated in lilitres: 1ml = 1cm3
read the volume of the liquid from scale looking straight at the bottom of the curved surface of the liquid. - 4Pressureforce/area
- 5Understand that the pressure at a point in a gas or liquid which is at rest acts equally in all directionsin stationary liquids and gases, pressure in any point acts in all directions
- 6Pressure differenceheight × density × g
