Why does food coloring diffuse faster in hot water vs cold water?
Molecules are more dense allowing them to move faster
Molecules have more energy allowing them to move faster
The food coloring attaches to water molecules, slowing them down
Molecules have more weight with more food coloring

The word malleable means
light reflects on surface
allows electricity to flow through easily
attracted to magnet
can be pounded or rolled into sheets
What should be the expected outcome of the experiment for both student groups completing this experiment? Provide a rationale for your answer.
There should be a greater change in mass because matter was destroyed.
The change in mass should be zero because matter cannot be created or destroyed.
The final mass should have been greater than the initial mass because matter was created.
Which observation indicates a chemical property?
slowly dissolves
turns cloudy
turns black
gritty
Where should plasma be placed in the States of Matter Model?
Space 1 because as plasma is heated it changes into a solid.
Space 2 because as a solid is heated it changes into plasma.
Space 3 because as a liquid is heated it changes into plasma.
Space 4 because as a gas is heated it changes into plasma.
Penny placed a tablet of baking soda in a cup of water. The tablet immediately began to bubble, fizz, and eventually dissolve.
Did a physical or chemical change occur and how do you know?
chemical; the tablet gave off a gas in the form of bubbles
chemical; the fizzing sound indicates a new substance was formed
physical; the tablet only dissolved in the water and formed a mixture
physical; the water can be boiled off and the tablet residue would be left

1-Elements; 2-Compounds; 3-Heterogeneous; 4-Homogeneous
1-Heterogeneous; 2-Elements; 3-Homogeneous; 4-Compounds
1-Compounds; 2-Heterogeneous; 3-Homogeneous; 4-Elements
You concluded that a physical change had occurred when the soda expanded as it froze.
What evidence BEST supports your conclusion?
The frozen soda tasted the same as liquid soda.
The can of soda was stuck to the freezer.
The soda formed no new substances.
The soda had come out of the can.
Chase buys a helium balloon for a friend’s birthday. As he walks out of the store, it starts snowing.
What do you predict will happen to the balloon, and why?
The balloon will expand and burst because helium is less dense
than cold outdoor air.
The balloon will shrink because the cold causes the helium atoms to slow down and move closer together.
The balloon will expand and burst because the rapid temperature change causes the helium atoms to move faster, increasing the pressure.
The balloon will shrink because the high humidity of the air outside the store exerts a greater pressure than the dry air inside the store.
Which of the following statements describes how mass was conserved in this chemical reaction?
There are two reactant molecules and three product molecules.
There are three reactant molecules and two product molecules.
The reactants have four hydrogen atoms and two oxygen atoms, and the products have the same atoms in two molecules of H2O.
The products have four hydrogen atoms and two oxygen atoms, and the reactants have the same atoms in two molecules of H2O.
Does this chemical reaction explain conservation of matter and why?
Yes, because atoms are the same in the reactants and products.
No, because atoms are not the same in the reactants and
products.
Yes, because molecules are the same in the reactants and
products.
No, because molecules are not the same in the reactants and
products.
Which BEST explains how pizza differs from milk?
Pizza is a mixture, and milk is a compound.
Pizza is a suspension, and milk is a solution.
Both are mixtures; pizza is heterogeneous, and milk is
homogeneous.
Both are solutions; pizza’s components can be seen, and milk’s
components cannot be seen.
