vocab 1
anything that takes up space and has mass
matter
force exerted on a surface divided by the total area ever which the force is exerted
pressure
movement of thermal energy from a substance at a higher temperature to a substance at a lower temperature
heat
anything that takes up space and has mass
matter
up word force exerted on an object immersed in a fluid
buoyant force
measure of the average kinetic energy of the individual particles of a substance
temperature
change of matter from a solid state to a liquid state
melting
a liquids resistance to flow
viscosity
freezing
states that the buoyant force on an object is equal to the weight of the fluid displayed by the object
Archimedes principle
matter that has a definite volume but no definite shape that can flow from one place to another
liquid
states that when a force is applied to a confined fluid, an increase in pressure is transmitted equally to all parts of the fluid
Pascals principle
a liquids resistance to flow
viscosity
the process of changing from a gas to a liquid
condensation
the process by which a liquid changes into a gas
vaporization
matter with a definite shape and volume; has tightly packed particles that move mainly by vibrating
solid
