The Tiny Stuff
This is the smallest 'building block' of all matter
What is an Atom?
This state of matter has no definite shape and no definite volume.
What is gas?
Slicing a piece of bread.
What is a physical change?
The process of a liquid turning to a solid
What is Freezing?
True or False: Mass cannot be created or destroyed.
What is true?
This is formed when two or more atoms bond together chemically.
What is a molecule?
This state of matter has a definite volume but takes the shape of a container.
What is liquid?
Baking a cake.
What is a chemical change? A new substance was created.
The process of a solid turning into a liquid.
What is melting?
True or false: If you freeze 50g of water, the ice cube will weigh 60g
What is false?
This term describes anything that has mass and takes up physical space.
What is matter?
What happens to the speed of molecules when a liquid turns into a gas?
What is speed up significantly?
Seeing bubbles form when you mix two liquids together.
What is a chemical change?
The process of a liquid turning into a gas
What is evaporation?
The mass/weight of a solution of 100g of water and 10g of sugar.
What is 110g?
True or False: Atoms never ever move and just stay in the matter frozen
What is false?
Which state of matter has a definite shape and a definite volume?
What is a solid?
List two possible signs of a chemical change.
What are:
color change, bubbles/gas productions, odor change. temperature change, new substance created?
The state a liquid becomes (eventually) if you take away heat/energy. Remember NO HEAT
What is a solid?
The state of matter of the 'missing' mass after you burn a log and weigh the ash.
What is gas/smoke went into the air?
Draw and describe what the molecules look like in a solid.
What are packed together tightly and vibrate in place? Drawing included.
If you move a gas from a small jar to a large beach ball, what happens to its volume?
It expands to the larger shape since it does not have a definite volume?
Because the composition of the popsicle (what makes up a popsicle) did not change, it is still flavored water with sugar, just in a different state.
What is gas?
True or false: during a chemical reaction, the number of atoms stays the same even if they rearrange.
What is true?
