How does density change?
Density usually changes when an object is heated or cooled - especially in the case of gases, or when there is a change of phase.
Some ways that density can change?
Pressure Temperature Changes in the molecular structure(chemical change)
How many cookies equal one pound?
Typically two dozen cookies equal one pound. This number changes with the size and density of the cookies being weighed.
How do you explain how graphs are used and what their advantages are?
Graphs show the relationship of one quantity to another. For example, it may show how the density of a material changes when the temperature is increased, or it may show the inflation depending on time. Vertically you show the quantity of interest (density, inflation) and horizontally what it depends on (temperature, time). You measure / look up / guess for each temperature the density, and draw a dot which is above the given temperature and to the right of the given density, and you do that for many densities.
What is a Boussinesq approximation?
The change in density of a fluid can be neglected if the temperature change in it is small. This assumption is however not applicable when buoyant forces are in consideration as gravity changes the specific weight of a fluid considerably.
What changes over time with density?
density changes when the substance changes.
Are color and density chemical changes?
Color and density are physical properties, not changes.
What happens to water as it changes state?
The density changes.
How does density changes from mantle to inner core?
by density change
If you have the same volume and the mass changes what happens to the density?
The density changes in direct proportion with the mass. A lesser mass results in a lesser density and a greater mass results in a greater density.
Does the density of water changes as it changes from a liquid to a gas?
yes it does
What is the density of 300 milliliters of water with 108 milliliters of water?
The density of water does not change when the volume changes. This is because density is a proportion of weight to volume. The density of water changes with temperature, but is approximately 1g/ml.
Changing the mass or volume of an object changes what?
Changing the mass or volume of an object changes its density. Density is defined as the mass of an object divided by its volume, so if either the mass or volume changes, the density will change accordingly.
What is the density of R134A?
Density of R-134a changes with respect to temperature and pressure.
How do changes in heat energy affect the density of earths mantle material?
How do changes in heat energy affect the density of earths mantle material
What happens to the density if you change the volume?
it changes
Will the density of a material always be the same regardless of its size if so why?
No, the density of a material is not always the same regardless of its size. Density is a property that is determined by dividing mass by volume, so as the size of an object changes, its volume also changes which can affect its density.
