IS Module 4 Review

Front

What is the most reactive non-metal?

Back

Chlorine (Cl) is the most reactive non-metal.

Front

What happens to a balloon filled with helium gas as the average kinetic energy of the helium particles increases?

Back

The gas atoms will strike the sides of the balloon more often.

Front

How can matter be categorized?

Back

Matter can be divided into two groups: pure substances and mixtures.

Front

What type of heat transfer occurs when a hot metal strip is placed on a block of metal with a lower melting point?

Back

Conduction, because the heat energy is absorbed by the metal atoms in the block.

Front

Who is correct about Mendeleev's periodic table, Darla or Harmony?

Back

Harmony is correct, because Mendeleev's model made predictions that came true.

Front

Define pure substance.

Back

A pure substance is a material that has a constant composition and consistent properties throughout.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that retain their individual properties.

Front

Explain the concept of conduction.

Back

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

Front

What is the significance of Mendeleev's periodic table?

Back

Mendeleev's periodic table helped establish the modern periodic table and made accurate predictions about undiscovered elements.

Front

What is kinetic energy?

Back

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