Because density is the relationship between weight and volume. If you're just increasing volume, making the stuff fluffier, then for each unit of volume the weight will be less.
Let's say you have a cup of cream. If you turn it into whipped cream it'll still weigh the same, but now it won't fit in the cup any more. More volume, same weight - lower density.
What else can I help you with?
When a substance changes from a solid to a liquid its density normally decreases. What is happening to the substance's mass and volume to cause this decrease in density?
A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.
Why does density decrease as temperature increases?
As temperature increases, the particles in a substance move faster and spread out more, causing the substance to expand and decrease in density.
When the loaf of bread is squeezed what will happen to its volume and density?
When a loaf of bread is squeezed, its volume will decrease as the air pockets within the bread compress. However, the density of the bread will increase as the mass remains the same but is now distributed in a smaller volume.
What will happen to pressure when gas expands and volume increases?
When a gas expands and its volume increases, the pressure of the gas will decrease. This is because pressure and volume are inversely proportional according to Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at constant temperature.
What happens to the density when heat is added?
When heat is added to a substance, it increases the kinetic energy of its particles, causing them to move faster and spread out. This leads to an increase in volume and a decrease in density since density is mass divided by volume.
In gases. What happens to the density of a given mass if the volume increases?
If the volume of a gas increases, the density of the gas will decrease. This is because density is mass divided by volume, so as the volume increases while the mass stays constant, the density will decrease.
What happens to the density as the volume increases?
If volume increases while mass remains the same, the density will decrease.
What happens to volume if density increases?
Density = mass / volume. Therefore, if volume increases and mass doesn't change, density will obviously decrease.
What happens to density if the volume increase?
must decrease
What is happening to the substances mass and volume to cause this decrease in density?
As the mass of a substance increases while its volume stays constant, its density will also increase. Conversely, if the mass of the substance stays constant while its volume increases, the density will decrease. This is because density is directly proportional to mass and inversely proportional to volume.
How is density affected if the volume of an object increases but its mass stays the same?
If the volume of an object increases but its mass stays the same, the density of the object will decrease. This is because density is calculated by dividing mass by volume, so if the volume increases without a corresponding increase in mass, the density will decrease.
Will density decrease or increase if mass stays same but volume increases?
density decreases
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.
What happens to mass r when volume increases?
If the volume of an object increases, and the mass remains the same, the density of the object will decrease. This is because density is calculated as mass divided by volume, so if volume increases and mass stays the same, density decreases.
What happened with density of gases on heating?
As gases are heated up, its volume increases, resulting in a decrease of density.
When air bubbles rises in water its volume increases what happens to its mass and density?
The mass of the air bubbles remains the same as they rise in water, but their density decreases. This is because as the volume of the air bubbles increases, they displace more water, causing their density to decrease relative to the surrounding water.
If the volume of an object increases what will the density do?
If the volume of the object increases while its mass remains constant, the density of the object will decrease. This is because density is calculated by dividing mass by volume, so if volume increases and mass stays the same, the resulting density will be lower.
