Matter
All matter has this, meaning it is made of stuff
What is mass?
If you add or remove this from matter it may change state
What is heat?
Boiling occurs when liquid turns into this
What is gas?
If an object is very dense it will have more of this in its volume
What is mass?
Heating a metal ball will stop it passing through a ring because of this
What is the particles move more causing it to expand?
All matter has this, meaning it takes up space
What is volume?
Particles are at their least active in this state of matter, merely vibrating in place
What are solids?
If you leave an ice cube in the sun it will do this
What is melt?
If an object is placed in a fluid that is more dense than the object, it will do this
What is float?
A change in the volume of a gas can be measured using this medical device
What is a syringe?
Matter is made of these
What are particles/atoms?
This state of matter has no fixed volume or shape
What is gas?
Cloud formation is an example of this process whereby a gas turns into a liquid
What is condensation?
Adding salt to water will do this to its density
What is increase it?
It is possible to make a simple thermometer using a conical flask and a straw because water does this
What is expand when heated?
Particles are constantly doing this
What is moving
If added to a vessel such as a box or a cup, this state of matter will start filling it from the bottom up
What is a liquid?
Dry ice (solid carbon dioxide) is used in smoke machines because it does this
What is sublimates (turns straight from solid to gas)?
Ships float despite being heavy because of this
What is they have low density/they have a large volume?
It is possible to create a rainbow density column using water, salt and food colouring because of this
What is adding different amounts of salt to the water will change its density
Particles stop moving at this temperature
What is -273.15oC?
This state of matter is rare on Planet Earth, it is hotter than gas
What is plasma?
This occurs when a gas turns into a solid
What is deposition?
The unit of density is one of these units which are expressed as one unit per another e.g. km/h
What are rates?
Liquids will take longer to run down a ramp when they are very this
What is viscous?
