Understanding the Concept of Boiling Point
The boiling point is a fundamental concept in chemistry that refers to the temperature at which a substance changes from its liquid state to its gaseous state. It is an important property to understand as it helps us determine the conditions under which a substance will vaporize.
Definition of Boiling Point
The boiling point of a substance is defined as the temperature at which its vapor pressure equals the atmospheric pressure. At this temperature, the substance undergoes a phase transition from a liquid to a gas. For example, water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level, where the atmospheric pressure is approximately 1 atmosphere.
Different substances have different boiling points due to variations in their molecular structures and intermolecular forces. For instance, zinc, a transition metal, has a boiling point of 907 degrees Celsius (1665 degrees Fahrenheit). This high boiling point is attributed to the strong metallic bonds between zinc atoms.
Factors Influencing the Boiling Point
Several factors influence the boiling point of a substance:
Molecular Weight: Generally, substances with higher molecular weights tend to have higher boiling points. This is because larger molecules have stronger intermolecular forces that require more energy to break.
Intermolecular Forces: The strength of intermolecular forces, such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces, affects the boiling point. Substances with stronger intermolecular forces will have higher boiling points.
Atmospheric Pressure: The boiling point of a substance is dependent on the surrounding pressure. At higher altitudes where the atmospheric pressure is lower, substances will boil at lower temperatures.
Presence of Impurities: Impurities in a substance can affect its boiling point. In some cases, impurities can raise the boiling point by interfering with the intermolecular forces.
Nature of the Substance: Different types of substances, such as metals, non-metals, and organic compounds, have varying boiling points due to differences in their chemical and physical properties.
Understanding the boiling point of a substance is crucial in various applications, such as cooking, distillation, and industrial processes. By knowing the boiling point, scientists and engineers can manipulate the conditions to achieve desired outcomes.

Why the Melting Point of Zn, Cd, Hg are Low
Zinc, along with cadmium (Cd) and mercury (Hg), belongs to a group of elements known as Group 12 elements in the periodic table. These elements are often referred to as the “coinage metals” due to their historical use in coins. One common characteristic of these metals is their relatively low melting points compared to other transition metals.
The low melting points of zinc, cadmium, and mercury can be attributed to their unique atomic structures and bonding. These elements have filled or nearly filled d orbitals, which results in weaker metallic bonding. As a result, the forces holding the atoms together in the solid state are not as strong, leading to lower melting points.
Additionally, the low melting points of these elements can be explained by their thermal properties. Zinc, cadmium, and mercury have relatively weak interatomic forces, which allows them to vaporize at lower temperatures compared to other metals. This is why these elements are often used in various applications that require low-temperature processes.
