foam of course
Foam has more volume per mass than gravel.
Density is weight divided by volume. Measure the weight (with a scale), calculate the volume (which is easy to do if the foam is rectangular in shape - you might even want to cut out a rectangular piece, if your foam has an irregular shape), and divide the weight by the volume.
Foam.
By squeezing the foam you are decreasing its volume, whereas its mass remains roughly the same. Therefor, as density is mass/volume, a decrease in volume results in and increase in density.
Shaving foam is a Liquid, it has a definite volume, but no definite shape. Solids have definite shape and gases have indefinite volume
Question: What is the effect of the acidity of potato juice on the volume of foam produced when hydrogen peroxide is added to potato juice? In this investigation, the prediction that if the acidity of potato juice is decreased then the volume of foam was increased was proven incorrect. Catalase is damaged by acid. The lowest foam volume was 24 ml with the highest acidity, pH6, However the highest foam volume was an average of 42 ml with the second lowest acidity level,pH8 The third highest volume was 35 ml with the second highest acidity level pH7, and the second lowest foam volume was 30 ml with the lowest acidity level pH9.
rock is much more dense than foam. It's like a full bottle of coke weiging more than an empty bottle of coke.
Density = mass/volume so in this case 200/1500 = 0.13 g/cm3
You Can Cut Memory Foam With Sicsorsthat squishes it and changes your cut...an electric hot knife will do a better job , but dont smell the greatest
Foam isn't a set substance. Foam is any material that can form a mass of small bubbles. The ratio of bubble volume vs base material can change, and that will change the properties of the foam.
Magnetism is the number of magnetic moments per unit of volume, so it is the volume of the magnet that determines magnetism. If an object has great weight and volume, the magnetism will be stronger. If an object has a great weight but lesser volume, the magnetism will be weaker.?æ
It's a 'high density' foam, which moulds itself to the ear canal. The density of the foam, coupled with the snug fit in the ear, limits the volume of sound reaching the eardrum.
