Physics - Kinetic Theory and Particle Model

Question 1

WHat is the equation for density?

Answer 1

density = mass/volume

Question 2

What is the definition of density?

Answer 2

the density of a substance is defined as its mass per unit volume

Question 3

How do you measure the density of a solid or liquid?

Answer 3

measure its mass and its volume, then use the density equation

Question 4

what is the density of water

Answer 4

1000kg/m3

Question 5

what happens to objects with density less than water?

Answer 5

they will float

Question 6

What is the density practical?

Answer 6

You must firstly measure the mass of the object and then fill water in a cylindrical jug and record the amount of water that was displaced when the object was put in. This is your volume, and then use the density equation to find the density.

Question 7

Why do you need to ensure that the object is fully submerged in water during the density practical?

Answer 7

TO ensure that all the objects volume is accounted for, because if it isnt, you will get an inaccurate volume measurement.
