Density - Physics Flashcards
1
Q
How to determine the density of irregular solid objects
A
- find the mass of the object using a balance
- Fill a eureka can with water, a eureka can has a spout, so water can flow out of the can
- place the object into the water. this will cause water to displace and flow out of the spout
- measure the volume of water displaced, the volume is the same as the volume of the object
- use the density equation

Q
how to determine the density of regular objects
A
- use a balance to determine the mass
- measures the length of the objects side and cube it
- divide the mass by volume

Q
how to measure the density of a regular object
A
- use a balance to measure the mass
- regular objects have dimensions which are easy to measure with a ruler
- multiply all the dimensions
do mass / volume

Q
what method do we use to find the density of an irregular object
A
as its hard to find the dimensions, we use displacement
