What is the difference between relative density and density, and how do they relate to each other?
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 another substance, usually water. Relative density is also known as specific gravity. The relationship between relative density and density is that relative density is a comparison of densities, while density is an absolute measure of mass per unit volume.
What is the relationship between molecular mass and vapour density?
The relationship between molecular mass and vapor density is that they are proportional to each other. Vapor density is defined as the mass of a vapor relative to the mass of an equal volume of air, while molecular mass is the mass of a molecule of a substance. Therefore, a higher molecular mass will result in a higher vapor density.
Is there any relationship between the volume of an object and its ability to float?
Yes. If mass remains the same, then density decreases as volume increases, and relative density determines "floatability".
What is the difference between relative density and density?
Nothing really. Density is stated by a material's kilograms per liter relative to pure water which is used to define a density of 1.
What is the difference between density and relative density?
Density: the ratio mass/volume for a material, expressed in kg/m3 (SI). Relative density: the ratio between the density of a material and the density of pure water at the same temperature.
Is the relationship linear between density and temperature?
The relationship between density and temperature is linear. In a thermal expansion, density will decrease and temperature increases and vice versa.
What is the relationship between density and specific gravity?
Specific gravity is the ratio of the density of a substance to the density of a reference substance. Density is a measure of how mass is distributed in a given volume, while specific gravity compares the density of a substance to that of water. In other words, specific gravity is a dimensionless quantity that provides a relative measure of how dense a substance is compared to water.
How do you find relative density of a solid using melde's apparatus?
To find the relative density of a solid using Melde's apparatus, you first need to determine the frequency of vibration of a stretched string driven by a tuning fork. You then immerse the solid in water and measure the change in the frequency caused by the addition of the solid while ensuring that the tension in the string remains constant. The relative density can be calculated by comparing the density of the solid to the density of water, using the formula ( \text{Relative Density} = \frac{\text{Density of Solid}}{\text{Density of Water}} ). This method relies on the relationship between the frequency of vibration, tension, and mass per unit length of the string.
How can you describe the relationship between mass and volume for these samples?
For substances with constant density, their mass is directly proportional to their volume. This means that as the volume of the substance increases, its mass also increases in a linear fashion. The relationship between mass and volume is described by the density of the substance, which remains the same regardless of the amount of the substance present.
