Density

Question 1

What is density

Answer 1

The mass per unit volume

Question 2

What is the equation for density

Answer 2

Density=mass/volume

Question 3

What is density measured in

Answer 3

Kg/M cubed or e

Question 4

How do you find the density of a liquid

Answer 4

Place the measuring cylinder on a balance then fill it with the liquid and measure the new mass the difference in masses is the mass of the liquid the volume can be read from the cylinder and the density using the eqaution

Question 5

How do you find the density of a solid

Answer 5

Measure the mass of the solid by placing it on the balance if the solid is a regular shape measure its dimensions using a ruler or a measuring tool and then using mathematical formula to find the volume Solid is a regular shape and mercy in water and most of the volume of the water displaced this is the volume of a solid find the density using the equation
