science fluids Flashcards
definition of solids
particles that have a strong attraction
definition of liquids
particles that have a strong attraction but can move past eachother
what is a gas
particles that have space between them, which allow the particles to spread out
contraction
when particles come closer together
expansion
when particles spread out or get bigger
slurry
a mix of a solid bits floating around in a liquid substance
dissolving
when the particles of one substance is more attracted to the particles in the other substance than they are to each other
temperature
average measure of kinetic energy within a substance
particles
small units that are always moving and bumping into each other.
air
a mixture of different types of particles that can spread out to all parts of a container
The use of oil in vehicles
helps moving parts,reducing friction, and cools the engine
Examples of fluids used in transportation
concrete, natural gas, coal, and paints
Examples of items that are often fluids as a part of production
water and oil
definition of mass
a measure of how much matter is in a substance
definition of volume
a measure of how much space a substance takes up
definition of thermal expansion
An increase in volume of a substance in response to an increase in the temperature
how cooling fluids affects the particles
as the temperature goes down, the particles slow down
why do some substances have to go through a fluid phase as there being produced?
It allows better control over the process and the final product
what r some fluids that r important to life on earth.
blood,water, sap, and lymph nodes
