Cumulative Review Aug - Sept

Front

What do elements in the same group/family of the periodic table have in common?

Back

They have the same number of valence electrons.

Front

What is the atomic number of an atom?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

How does mass affect the average kinetic energy of ice at the same temperature?

Back

The average kinetic energy of ice at the same temperature is equal, regardless of mass.

Front

What is the role of a thermometer in heat transfer experiments?

Back

A thermometer measures the temperature change, indicating heat transfer.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms.
