Why does alcohol float on the oil?
The alcohol is less dense than the water, so it floats up to meet the density needs.
How do you find mass when there is two given densities?
Density is the quotient of two physical properties: mass and volume. If Mass is needed, given Density then the Volume needs to be found in order to complete the equation: mass = density times volume in compatible units. For SI units, the units would be Density = kilograms per cubic meters Mass = kilograms Volume = cubic meters or try this To find mass divid the density
What organelle has increased in density in the cytoplasm of muscles that are being exercised in response to a greater demand for ATP production?
The mitochondria increase in density in the cytoplasm of muscles that are being exercised due to the increased demand for ATP production. Mitochondria are the primary organelles responsible for producing ATP through cellular respiration, and an increase in their density helps meet the energy needs of the active muscle cells.
Why do geographers study population density of a country in addition to it's total population?
Geographers study population density in addition to total population to understand how people are distributed within a country. This information helps to assess resource usage, urbanization patterns, infrastructure needs, and potential environmental impacts. Population density also provides insights into social dynamics, economic disparities, and issues related to land use and development.
Does density effect the temperature of liquids?
Yes it does affect, the denser the substance is, the lesser the temperature needed for it to be frozen . Hence . Density of a substance is indirectly propotional to the temperature it needs to be frozen.
What will stop a glacier from moving downhill?
There needs to be matter greater in size and density to stop it/
What will the density of any object be if they want that object you to float?
An object will float in water if its density is lower than water which means that for an object to float, its density needs to be less than ~1 gram/centimeter^3,
How does density change solid liquid and gas?
it changes it because of the particles floating round in witch it needs more space this is called density PS profession scientist
When density increases the number of molecules in a volume increases decreases varies or stays the same?
When density increases, the number of molecules in a volume stays the same. Density is defined as mass per unit volume, so as the mass increases, there needs to be a proportional increase in the number of molecules to maintain the density.
Why does alcohol float on the oil?
The alcohol is less dense than the water, so it floats up to meet the density needs.
Should a material have a higher or lower density to float in water?
A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel hull and the air inside the hull.
Why when density increase buoyancy force increase?
When density increases, the buoyancy force increases because the difference in density between the object and the fluid it is immersed in also increases. This difference in density creates a greater upward force, which is the buoyant force. This is because as the object's density increases relative to the fluid, more fluid needs to be displaced to counteract the weight of the object, resulting in a greater buoyant force.
An object with a mass of 1.32 g and a volume of 2.68 cm3 is placed in a tub of water Will it sink or float?
density = m/v d=1.32/2.68=0.49 density of water = 1. for an object to float it's density needs to be <1 here it quite obviously is. therefore it will float
What job where density is important?
Density is used greatly in many science jobs. A paint chemist needs to know the density of paint. In the USA this would be in pounds per US Gallon. In the rest of the world it would be in kg/liter. Aerospace engineers and many other designers need to know the density of the materials they are using.
How do you find mass when there is two given densities?

How can I increase bone density through diet?
For healthy bone density, the body needs minerals including boron, copper, magnesium, phosphorous, potassium, manganese and zinc. Adding foods rich in these substances to your diet may provide relief.
Why is population density important to a country?
Population density is important to a country because it affects various aspects of development and social systems. A high population density can put pressure on resources, infrastructure, and public services, while a low population density can limit economic activities and access to services. Understanding population density helps governments plan for housing, transportation, healthcare, and education needs appropriately.
