Density and Fluids
Measuring Density
100
Anything that has mass and volume
What is matter?
100
When solids turn into liquid
What is melting?
100
The energy of motion.
What is kinetic energy?
100
Mass of a given volume
What is density?
100
D = m÷v
What is the formula for finding density?
200
State of matter with definite shape and volume.
What is a solid?
200
The temperature where solids start to melt.
What is the melting point?
200
When matter expands as its temperature increases, due to the particles spreading out.
What is thermal expansion?
200
A form of matter, such as liquid and gases, that do not have a fixed shape.
What are fluids?
200
Two units usually used to measure the volume of liquid.
What are millilitres (mL) and cubic centimetres (cm³))?
300
Matter where the particles are slightly spaced apart, and can slide past each other freely.
What is liquid?
300
When gases change directly into solids.
What is sublimation?
300
When particles in matter slow down,and take up less space as they lose energy, causing the matter to shrink.
What is thermal contraction?
300
Generally speaking it is the densest item out of the three states of matter.
What is a solid?
300
Length x width x height
What is the formula for calculating volume?
400
Matter where particles take up the the space and shape of its surroundings.
What is gas?
400
The spaces between the particles change, which also causes the state of matter to change as well
What happens to matter if its temperature continues to rise or fall?
400
1. All matter is made up of very small particles 2. There is empty space between particles 3.Particles are constantly moving.
What is the kinetic molecular theory?
400
An exception to the rule that all substances in their solid form are denser than their liquid form.
What is ice?
400
Amount of space an object takes up when placed in fluid.
What is displacement?
500
The particles are attracted to one another. The strength of the attraction depends on the type of particle. (Name where this example is from)
What is an example of the particle model of matter?
500
When frost forms on a window on a very cold day.
What is an example of deposition?
500
Energy transfers from a substance with high energy to a substance with low energy.
What happens when two substances with different thermal energies come into contact?
500
An excellent example of how layering in density can happen within the same substance.
What is air?
500
Placing an object in liquid to see if it is denser or not.
What is layering?
