Volume, Mass, Density : Online IGCSE Physics Class
VOLUME, MASS, DENSITY IGCSE PHYSIC CLASS
What is the relationship between volume, mass, and density? Look at the formula below to understand how these 3 terms relate to each other.
Some IGCSE Questions to my students
E.g. of density calculation
Given a mass of 25kg with the volume of 200 metre cube. Find the density of the object?
Mass = 25/200=0.125 kg metre cube
A rectangular block of wood has dimension of 240mm x 20.5 cm x 0.04 m. Find its volume ?
Volume rectangular = Length x width x height
= 0.24 m x 0.205m x 0.04m
0.001968 meter cube
A rectangular block of wood has a dimension of 2.4m x 2.5 m x 0.04 m. Find its density if the mass of the object is 10kg?
Volume = 2.4 x 2.5 x 0.04 = 0.24 meter cube
Density = mass / volume
Density = 10 / 0.24 = 41.67 kg metre cube
What is the application of density?
- Oil and Water Don’t Mix. It’s a known fact that oil and water don’t mix, but what many people may not know is that the density of oil is what makes it float on top of water. …
- Helium Balloons. …
- Archimedes and Eureka! …
