Mass is the amount of matter. The mass is 300 atoms;
Density is how closely the mass is packed together.
Are the 300 atoms on a pin-head or in a football stadium.
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
The difference is that the mass density not effect by gravity but weight density effect by gravity. for example if mass density cotn in earth equal to 20 kg/m3 and weight density equal to 196.2 N/m3 this cotn will change the weight density in the moon but mass density not change because gravity moon diffrent to gravity earth mass density =mass/volume (no gravity) weight density= (mass * gravity)/volume (gravity)
A hypodense mass appears darker on imaging compared to surrounding tissues due to lower density, which may indicate fluid-filled or necrotic tissue. An isodense mass has similar density to surrounding tissues, making it harder to distinguish visually on imaging.
You can tell the difference in density between quartz and galena by measuring their mass and volume. Calculate the density by dividing the mass by the volume. Galena has a higher density than quartz, so the sample with higher density is likely to be galena.
It makes no difference. Density = mass / volume. You divide the mass by the volume. If the volume is greater than the mass your answer will necessarilybe less than one, but that is still the correct answer showing the density in terms of the units used.
Mass = Density x Volume Density = Mass/Volume Volume = Mass/Density
Heft refers to the weight or mass of an object, while density measures how much mass is contained in a given volume. Heft is the perceived weight when lifting an object, while density is a physical property relating mass to volume.
Density refers to the amount of mass per unit volume. In air, there are molecules present which contribute to the overall mass and density. In a vacuum, there are no molecules present, so the density is essentially zero.
The mass and density are very different.
Density is a measure of how much mass is contained in a given volume of a substance, while relative density compares the density of a substance to the density of a reference substance (usually water). Relative density is dimensionless and is often used to identify substances or determine their purity based on their comparison to a standard substance.
mass is the actual ''density'' of an object. whereas weight is determined by gravity and mass w=m*g hope this helps
In vacuum, neither mass nor density will make any difference. Otherwise, air resistance becomes relevant and objects with lower density fall lower.
