Question | Answer |
---|---|
Boiling Point | 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 |
Buoyancy | Ability of a fluid-a liquid or a gas-to exert an upward force on an object immersed in the fluid |
Diffusion | Spreading of particles throughout any given volume until they are uniformly distributed |
Heat of Fusion | Amount of energy required to change a substance from the solid phase to the liquid phase |
Heat of Vaporization | The amount of energy required for the liquid at its boiling point to become a gas |
Kinetic Theory | Explanation of the behavior of molecules in matter, states that all matter is made off constantly moving particles that collide without losing energy |
Melting Point | Temperature at which a solid begins to liquefy |
Pascal | SI unit of pressure |
Plasma | Matter consisting of positively and negatively charged particles |
Pressure | Amount of force exerted per unit area |
Thermal Expansion | Increase in size of a substance when the temperature is increased |
Viscosity | A fluid's resistance to flow |
