Solids Liquids Gas

Is a substance that has a definite shape and definite volume Solids are packed tightly together Some types of Solids are: Amorphous Solids Crystalline Solids

Is a substance that has definite volume but no shape When you pour liquid into container it takes the form of the container The particles in a liquid move more freely then in a solid The freely particles allow the liquid to flow which makes it a liquid

Is a substance that has no definite shape or volume When gas is moved from one place to another it bounces around off each other and off the container The particles in a gas move around freely.

Solid to a Liquid Liquid to a Gas Solid to a Gas Liquid to a Solid

The change from a solid to a liquid is called melting For a solid to change into a liquids involves an increase in thermal energy When something melts it melts at a melting point When a solid is melting the particles are vibrating so fast that the break free from their fix position

The change from a liquid to a gas is called vaporization For a liquid to change into a gas it has to have enough thermal energy Evaporation which is another form of vaporization only happens of the surface Boiling also another kind of vaporization happen underneath and on the surface

The change from a liquid to a gas is called condensation Condensation happens when the in a gas lose thermal energy to form into a liquid

The change from a solid to a gas is called sublimation Sublimation happens when solid gains enough energy that it forms into a gas with out forming it a liquid

When working with a gas, it is helpful to know it’s volume, temperature, and pressure. Volume-it is measured in cubic centimeters, milliliters, and other units.

Boyle’s law-Boyle found that when the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases.

When the temperature of a gas at constant volume is increased, the pressure of the gas increased, the pressure of the gas increases. when the temperature is decreased, the pressure of the gas decreases.

Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.

GRAPH-a diagram that tells how two variables, or factors that change, are related. PRESSURE-the gas is the force of its outward push divided by the area of the walls of the container. ORGIN-a line would pass through the point called (0,0) called the orgin.

Crystalline Solids: Solid that are made up of crystals and arrange in a pattern Amorphous Solids: Solids that are not arranged in pattern Fluid: a substance that can flow Surface Tension: is the result of an inward pull among molecules of a liquid that brings the molecules on a surface closer Viscosity: a liquids resistance to flowing Melting point: a specific temperature when melting occurs Boiling point : a temperature at which a liquid boils
