What happens to the particles when you add energy to matter?
Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). When heat is applied to a solid, its particles begin to vibrate faster and move farther apart.
What is the energy of the motion of the particles in the matter?
The energy of motion is called kinetic energy. The kinetic energy of particles of matter determines the state of matter. Particles of solids have the least kinetic energy and particles of gases have the most.
When you move the particles that make up matter farther apart the potential energy of the matter _____?
Potential energy typically increases when objects get farther apart and decreases when objects get closer together. The chemical potential energy of particles increases and decreases as the distances between particles increases and decreases.
How do the particles in matter move?
Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
Do particles have space between them?
The particles in a liquid usually are still touching but there are some spaces between them. The gas particles have big distances between them. Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other.
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. Liquid matter is made of more loosely packed particles. Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.
What does Bose-Einstein condensate look like?
It looks like a dense little lump in the bottom of the magnetic trap/bowl; kind of like a drop of water condensing out of damp air onto a cold bowl. When it first forms, though, the condensate is still surrounded by the normal gas atoms, so it looks a bit like a pit inside a cherry.
Is Bose-Einstein condensate dangerous?
The critical temperature under which a BEC forms is very close to the absolute zero. Getting into direct contact with extremelly cold things can seriously injure or even kill. But BEC is practically not dangerous. The process of cooling discards the majority of the particless.
What is Bose-Einstein condensate in simple words?
Bose-Einstein condensate (BEC), a state of matter in which separate atoms or subatomic particles, cooled to near absolute zero (0 K, − 273.15 °C, or − 459.67 °F; K = kelvin), coalesce into a single quantum mechanical entity—that is, one that can be described by a wave function—on a near-macroscopic scale.
What are the properties of Bose-Einstein condensate?
The most obvious property of a BEC is that a large fraction of its particles occupy the same, namely the lowest, energy state. In atomic condensates this can be confirmed by measuring the velocity distribution of the atoms in the gas.
What makes Bose-Einstein condensate unique?
A Bose-Einstein condensate is a group of atoms cooled to within a hair of absolute zero. When they reach that temperature the atoms are hardly moving relative to each other; they have almost no free energy to do so. Instead, the atoms fall into the same quantum states, and can’t be distinguished from one another.
What are the applications of Bose-Einstein condensate?
One application for BEC is for the building of so-called atom lasers, which could have applications ranging from atomic-scale lithography to measurement and detection of gravitational fields.
Does Bose-Einstein condensate have a definite shape?
They atoms in a liquid slide past each other. They have no definite shape but they have a definite volume. They are, BEC(Bose-Einstein Condensate), Solid, Liquid, Gas, and Plasma.
What is the most common state of matter in the universe?
plasmas
What’s the easiest way to add energy to matter?
Heat is probably the easiest energy you can use to change your physical state. The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point. When a solid reaches the temperature of its melting point, it can become a liquid.
What is the densest state of matter?
plasma
Which state of matter is the strongest conductor of electricity?
Plasma
Which state of matter Cannot be compressed?
Solids
| Property | Why |
|---|---|
| Solids have a fixed shape and cannot flow | The particles cannot move from place to place |
| Solids cannot be compressed or squashed | The particles are close together and have no space to move into |
Does density change with state of matter?
Density of a quantity of matter is its mass divided by its volume. External pressure pushes the atoms or molecules closer together and increased temperature usually expands the volume of the material, pushing the molecules apart. A change in the phase or state of a material usually results in a change in density.
Can two things have the same 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.
Will density change if volume changes?
Density is mass per unit volume. The relation between density and volume is directly proportional. That is any change in volume will result in the change in its density and vise-versa.
How does density change with pressure?
The density of a material varies with temperature and pressure. Increasing the pressure on an object decreases the volume of the object and thus increases its density. Increasing the temperature of a substance (with a few exceptions) decreases its density by increasing its volume.
Are pressure and density directly related?
Density and pressure/temperature Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases.
What is the relationship between fluid density and pressure?
d p d y = − ρ g . This equation tells us that the rate of change of pressure in a fluid is proportional to the density of the fluid.
Does density of fluid change with pressure?
When pressure increases, density increases. When the pressure decreases, density decreases.
