tendency of an object to float or rise in a fluid (air or liquid) due to the upward force exerted by the fluid
Buoyancy
: the change of state from a liquid to gas
Evaporation
: the change of state from gas to liquid
Condensation
: a change of matter from one form to another without a change in chemical properties
Physical Change
: the ratio of the mass of a substance to the volume of the substance
Density
a change from one state (solid or liquid or gas) to another by changing the physical arrangement of particles without a change in chemical composition
Change of state
: a measure of hot hot or cold something is; specifically, a measure of the average kinetic energy
Temperature
: The amount of force exerted per unit area of a surface
Pressure
: State of matter that consists of free-moving ions and electrons
Plasma
- The temperature and pressure at which a solid becomes a liquid
Melting Point
the ability of a substance to flow
Fluidity
: The capacity to do work
Energy
: The SI unit of pressure; equal to the force of 1 N exerted over an area of 1 m៱2
Pascal
: The capacity to do work
Energy
resistance of a liquid to flow; thickness or resistance to pouring
Viscosity
- anything that has mass and takes up space
Matter
: a change that occurs when one or more substances change into an entirely new substance with different properties
Chemical Change
: the upward force that keeps an object immersed in or floating on a fluid
Buoyant Force
: the total kinetic energy of a substance’s atoms
Thermal Energy
– force that holds atoms together in a compound
Chemical bond
the temperature and pressure at which a liquid becomes a gas
Boiling Point
: the capacity of a substance to combine chemically with one another.
Reactivity
: The laws that state the mathematical relationships between the volume, temperature, pressure, and quantity of a gas
Gas Laws
: the process in which a solid changes directly into a gas
Sublimation
an electrically neutral group of at least two atoms in a definite arrangement held together by chemical bonds
