Term | Definition |
---|---|
Kinetic theory | also known as molecular theory, is an explanation of how the particles in gases behave. |
Melting point | The temperature at which a solid becomes a liquid. |
Heat of fusion | The energy required to change a substance from solid to liquid at its melting point. |
Boiling point | The point of a liquid is the temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid. |
Heat of vaporization | The amount of energy required for the liquid at its boiling point to become gas. |
Sublimation | The process of a solid changing directly to a gas without forming a liquid. |
Plasma | Matter that had enough energy to overcome not just the attractive forces between its particles but also the attractive forces between its particles but also the attractive forces within its atoms. |
Thermal expansion | An increase in the size of a substance when the temperature is increased. |
Bvoyancy | The ability of a fluid- a liquid or a gas to exert an upward force on an object immersed in it. |
Pressure | A force exerted per unit area. |
Viscosity | The resistance of a fluid to flowing. |
Boyle's law | If you decrease the volume of a container of gas and hold the temperature constant, the pressure from the gas will increase. |
charles's law | The volume of a gas increases with increasing temperature as long as the pressure the gas does not change. |
