Density decreases when the mass of an object remains constant while its volume increases. This can occur due to temperature increases, which cause materials to expand, or when an object is placed in a less dense medium, allowing it to float. Additionally, changes in pressure can affect the volume of gases, leading to decreased density. Overall, the relationship between mass and volume is key to understanding density changes.
What else can I help you with?
Why does water's density decrease after potassium chloride salt is added?
The water density doesn't decrease.
When the fluids temperature increases does the density decrease decrease?
Yes!
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.
Do evaporation of salt water cause density increase or decrease?
During evaporation the density increase.
Do evaporation of salt water cause density to increase or decrease?
The density of water increase after evaporation.
What will happen to the density if you keep the volume the same and you decrease the mass?
If you decrease the mass while keeping the volume constant, the density of the object will decrease. Density is calculated by dividing mass by volume, so a decrease in mass with a constant volume will result in a lower density.
When a submarine pumps water out of its floating tanks its density decrease and it floats why does its density decrease?
Density = mass / volume. If the mass decreases, the density decreases.
Why does water's density decrease after potassium chloride salt is added?
The water density doesn't decrease.
What two things affect density?
The two main factors that affect density are the mass of an object and its volume. An increase in mass or a decrease in volume will lead to an increase in density, whereas a decrease in mass or an increase in volume will result in a decrease in density.
When the fluids temperature increases does the density decrease decrease?
Yes!
What happens to density if the volume increase?
must decrease
How does a change volume affect an objects density when mass stays the same?
With constant mass, a decrease in volume will increase the the density. Conversely, an increase in volume will decrease the density.
What is the effect of temp on density?
An increase in temperature results in a decrease in density.
What property will decrease if temperature increases?
Density will usually decrease in this case.
What effects of increase does density do?
Density decrease when the temperature is raising.
Does the surface energy increase or decrease with increase in planar density?
The surface energy decreases with an increase in planar density. This is because a higher planar density means more atoms are closely packed together, leading to a decrease in the number of surface atoms and therefore a decrease in surface energy.
Does evaporation of saltwater cause density to increase or decrease?
The density of the water increases.
