I have neither a fixed shape nor volume
Gas
Changing from a solid to liquid
Melting
Changing from a liquid to gas
Evaporation
My pencil breaks.
Physical change because there is no new substance created.
Matter
Anything that has weight and takes up space
I have volume, but no shape so I take the shape of the item I am placed in.
Liquid
I occur when the sun heats water
Evaporation
My spaghetti is ready to go in the pan because the water is more than 100 degrees celsius.
Boiling
Mixing ammonia with bleach.
Chemical change because there is a chemical reaction that creates a new substance.
Density
How much mass an item has.
I have a fixed shape and volume
Solid
I have reached 212 degrees.
Boiling
My cold drink has been sitting on the counter for a while and I have found sweat bubbles forming on the side of the glass.
Condensation
Mixing fat and water.
Chemical change because I am making a new substance.
Water Displacement Method for Measurements in Liquid
Place an object into a container with a measured volume. The weight can be determined by measuring the change in volume of the liquid matter from the current level to the original level.
My particles are in a regular pattern and packed tightly
Solid
I have fallen below 0 degrees celsius
Melting
Air is being sucked out of the vacuum. What is happening to the balloon inside? Why?
The balloon, inside, is expanding because the particles inside the balloon are expanding to fill the vacuum's removed air. Particles will fill the void that has been created.
Steel wool in water.
Chemical change because rust is forming on the steel wool in the water.
The standard units of measurement in the metric system
Liters, meters, and grams
As I am heated my particles become energized and begin to move further apart and I begin to move to another state
Liquid
The cold air on the ground has produced a morning dew.
Condensation
My mixed liquids in a test tube don't measure the same amounts I originally put into the test tube. Why?
All solutions have some empty space and the more dense liquid will fill the voided space in the less dense liquid.
My cotton ball found in my sink full of water.
Physical change because there is not a new substance formed.
Ice
Liquid and Solid
