Density is not a visual quality. But we can infer information about density by observing. For example moist air is lighter than dry air - that is why the clouds condense at higher altitudes, not at ground level.
{Explanation - H2O has an molecular mass of 28; O2 has an molecular mass of 32; N2 has an molecular mass of 34. Hence H2O vapour is lighter than O2 or N2.}

What do you mean relative density?
Relative density is a measure of the density of a substance compared to the density of another substance, usually water. It is calculated by dividing the density of the substance by the density of water. Relative density can help determine if a substance will sink or float in water based on its comparison to water's density.
How do you calculate the relative density of a substance?
To calculate the relative density of a substance, you divide the density of the substance by the density of water. The formula is: Relative Density Density of Substance / Density of Water. The relative density is a measure of how dense a substance is compared to water.
How are mass and volume related to the sinking and floating of an object?
An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.
What is the difference of relative density and density?
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.
How is the relative density of an object determined?
The relative density of an object is determined by comparing its density to the density of water. It is calculated by dividing the density of the object by the density of water. If the relative density is less than 1, the object will float in water; if it is greater than 1, it will sink.
What is the population density of Seen Winterthur?
The population density of Seen - Winterthur - is 1,555 people per square kilometer.
Why is the density of a substance independent of sample size?
Density is an intensive quantity which means it is independent of size. This can be seen from the definition of density. Density = mass/volume So if the sample size increases than so does the mass, but the density remains unchanged.
What do you mean relative density?
Relative density is a measure of the density of a substance compared to the density of another substance, usually water. It is calculated by dividing the density of the substance by the density of water. Relative density can help determine if a substance will sink or float in water based on its comparison to water's density.
Can the eukaryotic nucleus be seen with an light microscope?
The density of the nucleus can be seen using the light microscope, because the light microscope enlarges or makes the nucleus bigger.
What do you have to do in order to have a unit of measure for density?
You need its mass, and you need its volume. Then you divide its mass by its volume and that is how you express density. The most common unit of measure I have seen is grams/liter, if you use the metric system.
What is the cause for the flickering of objects when seen through hot air?
The speed of light changes if the density of medium changes. In hot air, the density is less so due to the change in speed of light, we think that it is flickering.
What is Boron's density at room temperature?
I've seen 2.34 g/cm^3 and also 2.46 g/cm^3
What is the most outer layer of the sun's atmosphere?
It is called the Corona, it's made up of a low density of Plasma and it can only be seen during eclipses
What is the function of HDL?
HDls- High Density Lipoproteins: They are seen as 'good cholesterol', as they are mainly protein. They bind to LDLs (bad cholesterol) and transport them to the liver, were they are stored. They are seen as helpful because they reduce risks of Heart related illnesses/diseases.
What is the difference density and relative density?
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
What is asymmetrical parenchymal density?
Asymmetrical parenchymal density refers to a difference in the density or appearance of breast tissue between the two breasts. This asymmetry can be seen on a mammogram and may indicate various conditions, such as benign changes, hormonal influences, or, in some cases, potentially abnormal findings that require further evaluation. It is important to follow up with a healthcare provider for proper assessment and management.
Is density a chemical property or a chemical property?
Density is classified as a physical property because the density of a substance can change when the substance changes state. Example: When water evaporates it is a physical change and the density changes. A chemical property is a property that describes its ability to react chemically with other substances and THEREFORE density is not a chemical property.
