Question | Answer |
---|---|
Boiling Point | The boiling 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. |
Buoyancy | Buoyancy is the ability of a fluid-a liquid or a gas-to exert an upward force on an object immersed in it. |
Diffusion | The spreading of particles throughout a given volume until they are uniformly distributed. |
Heat Of Fusion | The amount of energy required to change a substance from the solid phase to the liquid phase at its melting point. |
Heat Of Vaporization | The amount of energy required for the liquid at its boiling point to become a gas. |
Kinetic Theory | An explanation of how particles in matter behave. |
Melting Point | The particles of ice gain enough kinetic energy to slip out of their ordered arrangement. |
Pascal | The SI unit of pressure. |
Plasma | Matter consisting of positively and negatively charged particles. |
Pressure | Force exerted per unit area. |
Thermal Expansion | An increase in the size of a substance when the temperature is increased. |
Viscosity | The resistance to flow by a fluid. |
