Show the Animation Density of Liquids. Explain that to compare the density of oil and water you need to compare the weight of equal volumes of water and oil. Since the oil is lighter, it is less dense than water and floats on water.

Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids. The same amount of two different liquids you used in the container will have different densities because they have different masses.

Increase the volume of the object so that the object becomes less dense than the water. A great example of this is ice floating in water. The ship still displaces its weight in water, but because of the way the ship is constructed, it takes up more space than the volume of the water it displaces, so it floats.

No matter what size sample of water you measure, the relationship between the mass and volume will always be the same. Because D=m/v, the density is the same for any amount of water. Therefore, the ratio between the mass and volume is the same, making the density the same.

Density (d) depends upon the mass (m) and volume (v) of a substance. The mass depends upon the amount of matter in a substance, whereas volume is the amount of space that a substance takes up. Mathematically, density is equal to a ratio where d = m/v.

The size, mass, and arrangement of atoms affect the density of a substance. How might these factors work together to cause a substance to have a high density? A substance with smaller more massive atoms that are close together is going to have a higher density.

Long answer: Density is generally regardless of how big or small a substance is and is neither dependant on its shape. A statue made of gold and a brick made of gold might have different masses and volume but they have same density. Mind you, two different materials of same shape and size do not have the same density.

So Pure materials ,they can not have same densities. (Assuming they are not isotopes of each other.) But mixtures, compounds or different phases can have same densities. That being said, I would have to say that elements will all have individual weights and densities, but compounds can be made up in any number of ways.

The density of a material varies with temperature and pressure. This variation is typically small for solids and liquids but much greater for gases. Increasing the pressure on an object decreases the volume of the object and thus increases its density.

The pressure is the measure of force acting on a unit area. Density is the measure of how closely any given entity is packed, or it is the ratio of the mass of the entity to its volume. The relation between pressure and density is direct.

The ideal gas law where n is the number of moles of gas and R is the universal gas constant. So pressure is proportional to the number of moles of gas, not the mass of the gas. Pressure is not dependent on mass.

Oils are the least dense of the three you mention. Most oils have a density around 90% that of water. Household vinegar consists almost entirely of water, but with some acetic acid molecules dissolved in it. In general, dissolving stuff in water makes it more dense, making vinegar the densest of the three.

Since the oil is lighter, it is less dense than water and floats on water.

Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.

Explain why heating a block of metal causes it to become less dense. It will become less dense because heating gives particles more kinetic energy, and as they move faster particles become further apart from each other, effectively decreasing the density of the material as a higher proportion of it is empty space.

Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. Because ice is less dense than water, it is able to float at the surface of water.

An equal mass of water in the same sun will not become nearly as hot. We would say that water has a high heat capacity (the amount of heat required to raise the temperature of an object by 1°C.)…Heat Capacity and Specific Heat.

Specific heat of milk is less than that of water ( This is analogues to thermal conductivity is more) . Therefore milk cools faster. However, the boiling point of milk is close to the boiling point of water, which is 100°C or 212°F at sea level. Milk contains additional molecules so it would be slightly higher.

Researchers have discovered that tantalum carbide and hafnium carbide materials can withstand scorching temperatures of nearly 4000 degrees Celsius. These materials may enable spacecraft to withstand the extreme heat generated from leaving and re-entering the atmosphere.

Heat Resistance: Like granite most quartzite is very heat resistant and can withstand hot pots and pans. Beauty: Because of its similarities to sandstone and marble, quartzite provides an elegant and luxurious feel with its incredible veining and beautiful color.

A material that does not let heat and electricity travel through it easily is known as an insulator. In many situations, we want to trap heat and slow down its flow, or stop the flow of electricity and prevent electric shocks. Plastic, rubber, wood, and ceramics are good insulators.

Rubber is poor conductor . space between the molecules which makes it a very bad insulator. Its electrons are locally bound and not free as is the case with metals. radiation, conduction, or convection.

The rubber band actually expands when it gets colder! This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.
