solids,liquids,gasses
a form of matter that has no shape
What is a liquid?
something that doesn't have a shape or free to flow
what is a fluid?
it is the upward force that a fluid exerts on an object
what is buoyancy?
if pressure is exerted on a fluid it will be evenly distributed throughout the fluid.
what is pascals law?
is a measure of how much matter is in an object.
what is mass?
when a solid turns into a gas without turning into a liquid first?
what is sublimation?
what happens when a fluid has a high viscosity
what is it flows more slowly?
submarines control this to sink or float by emptying tanks with it
what is water?
flow rate = volume of fluid passing/time
what is the measure of flow rate?
the amount of matter in an object and the other is how much force of gravity is put on the mass of an object
what is the difference between mass and weight?
a gas cools down making the particles move slower and get closer together
what is condensation?
friction,cohesion,adhesion,temperature,concentration,particles size
all the things that can affect the viscosity of a liquid?
archimides discovered his principle while doing this activity
what is taking a bath?
pascals law is especially useful in machines that work by using this kind of fluid
what is a liquid?
objects that are less dense then water will do this when placed in water
what is float?
which state of matter has particles that are tightly packed and which has particles that are widely spread out
what are solids, and gasses?
this fluid in your body carries oxygen to cells and removes carbon dioxide
what is blood?
this happens to the buoyant force when an object displaces more fluid
what is the buoyant force increases?
This device uses Pascal’s Law to multiply force, often found in car brakes and hydraulic lifts.
What is a hydraulic system?
density is calculated by dividing this by volume
what is mass?
This phase change happens when water vapor in the air cools down and turns back into liquid water like on the outside of a cold glass.
What is condensation?
when the temperature increases this usually happens to a fluids viscosity
what is it decreases?
This is the formula to calculate buoyant force, based on Archimedes’ principle.
What is buoyant force = weight of displaced fluid?
This term describes the volume of fluid that passes a point in a given amount of time.
What is flow rate?
this property explains why some objects float while other sink
what is density?
