1st Semester Exam prep

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the square of its velocity.

Front

What is the order of kinetic energy from low to high in the following states: Solid, Liquid, Gas?

Back

Solid (S), Liquid (L), Gas (G).

Front

What variables must remain constant in a heat conduction experiment?

Back

The temperature and time the material was exposed to the heat.

Front

What does the conservation of mass state in chemical reactions?

Back

The reactants and products have exactly the same atoms.

Front

How can you identify an atom using the periodic table?

Back

You can reference the periodic table to find the element that has an atomic number equal to the number of protons in the atom.

Front

What is a compound?

Back

A compound is a substance formed when two or more elements are chemically bonded together.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of atom, while a compound is made of two or more different types of atoms chemically bonded.

Front

What is heat conduction?

Back

Heat conduction is the transfer of thermal energy through a material without the movement of the material itself.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number and properties, allowing for easy identification and comparison.
