Test Description: FCAT PRACTICE
Instructions: Answer all questions to get your test result.
1) Matter can undergo physical and chemical changes. A physical change is a change of matter from one form to another without a change in the identify of the substance. Which process is an example of a physical change?
A
wood burning
B
ice melting
C
milk souring
D
metal rusting
2) Pablo notices that ice cream begins to melt when left out at room temperature. What is Pablo observing?
A
formation of a new substance
B
physical change
C
chemical reaction
D
chemical change
3) Gallium is a metal. If you hold a solid piece of pure gallium in your hand, your body warmth will melt the gallium. What is this an example of?
A
physical change
B
chemical change
C
absorption
D
displacement
4) In the laboratory, Austin is given a mixture of iron filings, sand, and salt. To separate the mixture, Austin uses a magnet, boiling water, and a filter. Which statement is true about the process Austin uses to separate this mixture?
A
Austin uses neither physical nor chemical changes to separate the mixture’s components.
B
Austin uses only chemical changes to separate the mixture’s components.
C
Austin uses both physical and chemical changes to separate the mixture’s components.
D
Austin uses only physical changes to separate the mixture’s components
5) A molecule is involved in a chemical reaction, causing the arrangement of its atoms to change. What is the result of this process?
A
new atoms are formed
B
the mixture is separated into its component parts
C
a different molecule with different properties is formed
D
bonds are neither formed nor broken, so mass is conserved
6) There are several differences between chemical and physical changes. Which process is an example of a chemical change?
A
alcohol evaporating from a cotton swab
B
a piece of wood shrinking as it dries out
C
steam rising from a boiling pot of soup
D
a metal railing rusting in damp weather
7) Alison finds the total mass of a sample of baking soda, a balloon, and a glass container with vinegar in it. She adds the baking soda to the vinegar and immediately places the balloon over the mouth of the container. After the reaction is complete,
A
The mass does not change because chemical changes observe the law of conservation of mass.
B
Mass is lost during the reaction because the gas can change in volume but baking soda and vinegar cannot.
C
Mass is lost during the reaction because the gas is less dense than the baking soda or vinegar.
D
Mass is gained during the reaction because a chemical change is taking place.
8) Rita wants to make some toast for breakfast, which she knows involves a chemical change to the bread. She puts a slice of bread in the toaster, but, after 10 minutes, she notices that the sides of the bread are black. What caused this chemical change
A
an increase in temperature
B
a decrease in temperature
C
the size of the bread
D
the type of bread
9) Which types of changes observe the law of conservation of mass?
A
physical and chemical changes
B
only physical changes
C
only chemical changes
D
only changes of state
10) When paper is burned, the mass of the remaining ash is less than the mass of the original paper. Which statement best explains this result?
A
Some of the matter is destroyed during the reaction.
B
The mass of the ash cannot be accurately determined.
C
Some of the products of the reaction were given off as a gas.
D
The ash has less volume than the paper.
