Upward force exerted on an object immersed in a fluid
Archemides principal
The bouyant force on an object is equal to the weight of the fluid displaced by the object
Condensation
The opposite of vaporization, the process of changing from a gas to a liquid
Density
Mass divided by volume
Freezing
Change of matter from a liquid to a solid
Gas
Matter that doesn’t have definite shape; has particles that move at high speeds in all directions
Heat
thermal energy that flows from higher temperature to a lower temperature
Liquid
Matter with definite volume and takes the shape of container
Matter
Anything that takes up space and had mass
Melting
Change of matter from a solid to a liquid
Pascals principle
Term referring to the pressure applied at any point to a confined fluid being transmitted unchanged throughout the fluid
Pressure
The amount o force applied per unit of area
Solid
Matter w/ definite volume and shape and has tightly packed particles
Surface tension
Uneven forces acting on particles on surface of a liquid
Temperatures
Average kinetic energy of individual particles
