Describing Fluids
This is defined as anything that flows
What is a fluid?
This term describes the speed at which fluids move from one point to another
What is flow rate?
This is described as the energy of motion
What is Kinetic Energy?
This is described as the amount of mass in a defined unit of volume
What is density?
This is the formula describing density
D=M/V?
This has a definite shape and volume
What is a solid?
This term describes a fluids thickness and resistance to flow
What is viscosity?
If the temperature of a liquid is decreased then the viscosity of the liquid is ________
What is increased?
Between 5 kg of iron and 5 kg of Styrofoam, this substance has the greater volume
What is Styrofoam?
Placing an irregularly shaped solid in water and measuring the rise of the water is a tricky way to measure volume and is known as this
What is displacement?
This has a definite volume but an indefinite shape
What is a liquid?
Of water, dish soap and molasses, this is the fluid with the highest viscosity
What is molasses?
If the attractive forces of particles in a substance are low, then the fluid will have a _____________ viscosity
What is low?
In general solids are more dense than these
What are liquids or gases?
An object with a mass of 10g and a volume of 2.0 cm3 has this density
What is 5.0 g/cm3?
This change of state occurs as particles gain energy and move farther apart changing from a liquid to a gas
What is evaporation?
A substance with a low flow rate has a __________ viscosity
What is high?
Increasing the concentration of particles causes more collisions. As a result viscosity does this.
What is increases?
In general, solids are more dense than liquids, therefore most solids do this in liquids
What is sink?
An object with a mass of 10g and a density of 2.16 g/cm3 has this volume
What is 4.63 cm3?
This is made up of 5 points and describes the characteristics of all matter
What is the Particle Theory of Matter?
This is the flow rate of a substance that travels 10 cm in 20 seconds
What is 0.5 cm/sec?
If the temperature of a gas is increased then the viscosity of the gas ________
What is increased?
This is an example of a very dense liquid on which most solids will float
What is mercury?
An object with a volume of 1500ml and a density of 0.002 g/cm3 has this mass
What is 0.3g?
