States of Matter Questions
-
A state of matter in which the particles are fixed in a regular pattern
-
A state of matter in which the particles are free to move around
-
A state of matter in which the particles are attracted to each other but can still move around
-
A state of matter in which the particles are repelled from each other
B
Correct answer
Explanation
A liquid is a state of matter in which the particles are free to move around.
What is the chemical formula for water?
A
Correct answer
Explanation
The chemical formula for water is H2O, which means that each molecule of water contains two hydrogen atoms and one oxygen atom.

B
Correct answer
Explanation
Oil paints are made with pigments suspended in a drying oil, typically linseed oil or poppy seed oil.
What is the main component of watercolor paints?
-
Oil
-
Acrylic
-
Gum Arabic
-
Tempera
C
Correct answer
Explanation
Watercolor paints are made with pigments suspended in a water-soluble binder, typically gum arabic.
Which state of matter has a definite shape and volume?
A
Correct answer
Explanation
Solids have a definite shape and volume because the particles are held together by strong intermolecular forces.
Which state of matter has a definite volume but no definite shape?
B
Correct answer
Explanation
Liquids have a definite volume because the particles are held together by strong intermolecular forces, but they do not have a definite shape because the particles can move around freely.
Which state of matter has no definite shape or volume?
C
Correct answer
Explanation
Gases have no definite shape or volume because the particles are not held together by strong intermolecular forces and can move around freely.
Which state of matter has the highest density?
A
Correct answer
Explanation
Solids have the highest density because the particles are packed together tightly.
Which state of matter has the lowest density?
C
Correct answer
Explanation
Gases have the lowest density because the particles are not packed together tightly.
Which state of matter has the highest kinetic energy?
C
Correct answer
Explanation
Gases have the highest kinetic energy because the particles are moving around freely.
Which state of matter has the lowest kinetic energy?
A
Correct answer
Explanation
Solids have the lowest kinetic energy because the particles are held together by strong intermolecular forces.
Which state of matter is most compressible?
C
Correct answer
Explanation
Gases are most compressible because the particles are not held together by strong intermolecular forces.
Which state of matter is least compressible?
A
Correct answer
Explanation
Solids are least compressible because the particles are held together by strong intermolecular forces.
Which state of matter has the lowest specific heat capacity?
C
Correct answer
Explanation
Gases have the lowest specific heat capacity because the particles are not held together by strong intermolecular forces and require less energy to raise their temperature.
Which state of matter is most likely to undergo a phase change?
B
Correct answer
Explanation
Liquids are most likely to undergo a phase change because they are at an intermediate state between solids and gases and can easily change from one state to another.
