What is the definite shape and volume for solid, liquid, and gas? Solids have the lowest amount of kinetic energy. The particles that make up a solid are packed close together and are rigid, so that they can only vibrate in place. Solids have a definite shape and a definite volume. Liquids have more kinetic energy, so their particles are less rigid and can slide around one another, which allows liquids to flow. Liquids have no definite shape, so that they take the shape of their container, except for the surface, which is flat, but they do have a definite volume. Gases have more kinetic energy than liquids, so their particles move very rapidly. Gases expand to fill their container, so they have no definite shape and no definite volume.

- Liquids. 1  Liquids can flow or be poured easily. They are not easy to hold. 2  Liquids change their shape depending on the container they are in. 3  Even when liquids change their shape, they always take up the same amount of space. Their volume stays the same.  Heating a liquid can turn it into a 1  gas. Cooling a liquid can turn it into a solid.

The Importance of Homeostasis Particles in liquids and gases move about randomly in all directions. In an area of high concentration, particles will escape from the concentrated area to places where there are fewer or no particles. Very few particles leave an area of low concentration to go to an area where the concentration is higher. Diffusion is the movement of particles from an area of high concentration to an area of low concentration. This is described as moving down a concentration gradient.

Q & A: Turning water into ice at room temperature The molecules in a solid are locked in a rigid pattern in space and for most substances are closer together on average in the solid than they are in the liquid. Water is an exception to this -- it expands when it freezes at ordinary pressure, which is why ice floats on the top of a frozen lake.

- The particles in fluids (liquids or gases) can move from place to place when heated. Convection occurs when particles with a lot of heat energy move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Click here for an example of convection currents in a gas. Click here for an example of convection currents in a liquid.

Unit 8 In a gas, particles move much faster and the attractive forces are weaker than the attractive forces in a liquid and a solid. When the distance between particles change then the attractive forces also change. Forces between particles in a gas. The attractive forces between particles in a gas are weak or absent.

Liquid A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Water is, by far, the most common liquid on Earth. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed.

How many states are there in the world? They also have a definite volume. The particles of a solid are already so tightly packed together that increasing pressure will not compress the solid to a smaller volume. Liquids. In the liquid phase, the particles of a substance have more kinetic energy than those in a solid.

- * Usually, the density of a substance is very high in solid state than other states. However there are exceptions like water. * Solid are practically incompressible since the particles are closely packed. LIQUID STATE * The liquid state has fixed volume but has no definite shape. It adapts to the shape of container. Indeed, it tends to occupy the bottom portion of the container due to gravitational pull and has free surface at the top. * The forces of attraction are less when compared to that of solid state.

- Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.n such situations, water still moves across membranes by simple diffusion, but the process is important enough to warrant a distinct name-osmosis. Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane.

Solid Basics Even when you grind a solid into powder, you will see tiny pieces of that solid under a microscope. Liquids will flow and fill up any shape of container. Solids like to hold their shape. In the same way that a large solid holds its shape, the atoms inside of a solid are not allowed to move around too much. Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want. The molecules in a solid are stuck in a specific structure or arrangement of atoms.

- Like liquids, gases can flow but, unlike solids or liquids, gases will not stay where they are put. They have no set shape or volume, and they expand in every direction to fill completely whatever container they are put into. If the container has no lid, the gas escapes.

In and out of cells Particles (molecules and ions) in solution move around colliding with one another constantly and the walls of the container holding the solution. The particles are said to have translational energy. The movement is random, but there is a net movement from regions where there are lots of particles to ones where there are fewer particles.

Particle Theory The particles need energy to overcome the attractions between them. As the liquid gets warmer more particles have sufficient energy to escape from the liquid. Eventually even particles in the middle of the liquid form bubbles of gas in the liquid. At this point the liquid is boiling and turning to gas.
