Density

Question 1

What is Density?

Answer 1

Density is the measurement of a mass in a given volume

Question 2

Density Equation

Answer 2

Density = Mass / Volume

Question 3

Density experiment of Regular objects

Answer 3

1. To work out the mass, place the object on a pan balance.
2. To work out the volume of a regular object, use a ruler to measure its dimensions.
   ( L x W x H)

Question 4

Density experiment of Irregular objects

Answer 4

1. Measure the mass with a pan balance.
2. To work out the volume:
   Fill up a eureka/displacement can with water just above the spout
   Place a measuring cylinder at the spout of the can
   Gently put the Irregular object in the can.
   The amount of water that gets displaced into the measuring cylinder is the volume of the object.
3. Substitute the measurements into the formula to work out the density

Question 5

Density experiment of Liquids

Answer 5

1. Place the measuring cylinder onto the pan balance.
2. Add 10ml of water to the cylinder and record its mass
3. Add another 10 ml and record its total volume and mass
