Can objects have the same density?
So yes, two objects of the same substance, but with a difference size and/or shape can have the same density, it all comes down to the weight, the volume and the temperature to determine your density, that is assuming your object isn’t hollow of course.
How can these objects all have the same mass but have different densities?
However, for two objects of the same volume – if their densities are different then their masses will also be different. The definition of “density” is mass divided by volume – so if the volumes are the same and the densities are different then the masses must be different.
What determines the density of an object?
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).
Can something have no density?
Question: If an object has 0 density therefore gravity has no effect on it. So if an object has 0 density it must have no mass, therefore it wouldn’t exist.
Which item is the least dense?
The least dense substance is the gas hydrogen. Its atomic mass is 2 grams per mole. At Standard Temperature and Pressure one mole has a volume of 22.4 liters. Since density is mass over volume the density of the hydrogen gas is 2 grams divided by 22.4 liters.
Which liquid is the least dense?
Hydrogen has the lowest molecular weight, so liquid hydrogen would be the least dense of all liquids at its own boiling point.
Is low density heavy or light?
If something is heavy for its size, it has a high density. If an object is light for its size it has a low density.
What is considered a low density?
Low density housing typically refers to residential areas occupied primarily by single-family homes or buildings with a small number of units. Low density areas usually have more green space but do not have as much commercial space nearby.
Which state of matter has the lowest density?
gases
Does all matter have density?
Density and other intensive properties Many materials expand when they are heated. Because a material that expands takes up a larger volume, its density decreases. This phenomenon occurs in all forms of matter: for example, solids, liquids, and gases.
Which has more density solid or liquid?
Density is how close together the molecules are in a substance. Liquids are usually less dense than solids but more dense than air. The farther apart the molecules are, the less dense the water is. A solid is usually denser than a liquid, so you might expect an ice cube to sink in water.
Which state of matter has only vibrational motion?
In a solid, the particles (ions, atoms or molecules) are closely packed together. The forces between particles are strong so that the particles cannot move freely but can only vibrate. As a result, a solid has a stable, definite shape, and a definite volume.
What are the 7 states of matter?
The seven states of matter that I am investigating are Solids, Liquids, Gases, Ionized Plasma, Quark-Gluon Plasma, Bose-Einstein Condensate and Fermionic Condensate.
Is there a state of matter in which the particles are not moving at all?
Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
Which state holds its own shape?
Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.
What brings about a change of state of matter?
Changing states of matter occur when matter loses or absorbs energy. When a substance absorbs energy the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough, that they change form.
