What is the process of a liquid turning into a gas called?

Back

Evaporation.

Front

What type of intermolecular forces do molecular solids have?

Back

Weak intermolecular forces.

Front

How can differences in crystal shape affect the properties of raw materials?

Back

They can alter the melting point.

Front

When do ionic solids conduct electricity?

Back

When melted or dissolved in water.

Front

How do ionic compounds compare to molecular compounds in terms of melting and boiling points?

Back

Ionic compounds have higher melting and boiling points than molecular compounds.

Front

What is the definition of evaporation?

Back

The process by which molecules in a liquid state gain enough energy to enter the gaseous state.

Front

What are ionic compounds?

Back

Compounds formed from the electrostatic attraction between positively and negatively charged ions.

Front

What is the significance of crystal shape in materials science?

Back

Crystal shape can influence physical properties such as melting point, hardness, and solubility.

Front

What is the difference between ionic and molecular solids in terms of conductivity?

Back

Ionic solids conduct electricity when melted or dissolved, while molecular solids do not.

Front

What are the characteristics of molecular solids?

Back

Molecular solids have weak intermolecular forces, lower melting points, and do not conduct electricity.
