What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

How does temperature relate to the kinetic energy of air particles?

Back

As temperature increases, the average kinetic energy of air particles also increases, meaning they move faster.

Front

What is the Continental Drift Theory?

Back

The Continental Drift Theory suggests that continents were once connected and have since drifted apart, similar to pieces of a puzzle.

Front

What evidence supports the Continental Drift Theory?

Back

Evidence includes similar rock formations, fossil records, and glacial markings found on continents that are now separated.

Front

What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means. Examples include hydrogen (H) and oxygen (O).

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together. For example, water (H2O) is a molecule made of two hydrogen atoms and one oxygen atom.

Front

What is a compound?

Back

A compound is a substance formed when two or more different elements are chemically bonded together. For example, H2O is a compound.

Front

What is a chemical formula?

Back

A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound.

Front

What is the difference between an atom and a molecule?

Back

An atom is the smallest unit of an element, while a molecule is a group of two or more atoms bonded together.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties.
