Chemistry and Physical Changes Quiz

Properties and Characteristics of Matter

• If a food tastes bitter, it probably has an ingredient that is a base.
• If a food tastes sour, it probably has an ingredient that is an acid.

Units of Measurement

• The abbreviation for millimeter is mm.

Chemical Reactions

• During an exothermic reaction, energy is released.
• A nail rusting is an example of a chemical change.

Elements and Compounds

• Oxygen and hydrogen are examples of elements.
• A chemical formula tells the elements and ratio of atoms in a compound.

Energy

• The energy of a stretched or compressed object is elastic potential energy.
• Energy of matter due to its position is potential energy.
• We have potential energy sitting on our bikes at the top of the hill.
• Energy can be classified into types such as thermal, kinetic, and electromagnetic.

Forces and Motion

• A push or pull exerted on an object is a force.

Atomic Structure

• The part of the atom that is responsible for most of the mass of the atom is the nucleus.
• The particle that takes up most of the volume of an atom is the electron.

Physical Changes

• Braiding hair is a physical change.
• Solids and liquids have at least one similar property.

Energy and Work

• Energy is the ability to cause work or change.
• The amount of matter inside an object is its mass.
• Power is not the same as energy or work.
