If two objects have the same volume and density do they ave the same mass?
Yes, if two objects have the same volume and density, they will have the same mass. This is because mass is calculated by multiplying density and volume; therefore, having the same density and volume means the objects will have the same mass.
Why do two samples with the same substance with the same volume HAVE to have the same mass?
Because they are of the same substance they have the same density density = mass/volume
If A sponge and a brick that are the same size they have the same what?
no; they have the same volume but their mass is quite different; density is mass/volume and the sponge has much lower density
If mass stays the same and density decreases then the volume does what?
If mass stays the same and density decreases, then the volume must increase. This is because density is mass divided by volume, so if density decreases while mass remains constant, the volume must increase to maintain the same mass.
Can objects with the same mass have the same volume?
no
How do mass and volume work together?
Mass and volume are related through density, which is the amount of mass per unit volume of a substance. An object with a larger volume but the same mass as a smaller object will have a lower density. Conversely, an object with the same volume but more mass will have a higher density.
Why can two objects with the same mass and volume have the same density?
Density is a property that represents the compactness of a substance. If two objects have the same mass and volume, it means that they have the same amount of material packed into the same amount of space, resulting in the same density. Density is calculated by dividing mass by volume, so if mass and volume are equal, density will also be equal.
Why does mass and volume affect density?
The density of a substance is its mass divided by its volume. So for the same volume the higher the mass, the higher the density.
How does decreasing the mass change the object's density?
Decreasing the mass of an object while keeping its volume constant will increase its density. Density is calculated by dividing mass by volume, so as mass decreases and volume remains the same, the density value will increase.
Is volume and mass the same thing?
No, volume and mass are not the same thing. Volume is the amount of space occupied by an object, while mass is the amount of matter in an object. Mass is a measure of the quantity of atoms in the object, whereas volume is a measure of the space the object occupies.
How can a small object be more dense if it does not have the most mass?
You seem to be thinking that density is the same as mass, or proportional to mass. That is not the case. Density is mass divided by volume. For example, two objects of the same material have the same density. The larger object will have more mass (in the numerator), but it will also have more volume (in the denominator).
Changing the mass or volume of an object changes its density and?
Changing the mass or volume of an object will alter its density. If mass increases and volume stays the same, density will increase. Conversely, if volume increases and mass stays the same, density will decrease.
