Options:

1.Higher condensation temperature
2.Lower condensation temperature
3.Similar condensation temperature
4.Unrelated condensation temperature

Answer 1

Heavy elements, such as iron and silicon, have a Higher condensation temperature compared to light elements, such as hydrogen and helium. Option 1

Step-by-step explanation:

Heavy elements, such as iron and silicon, have a higher condensation temperature compared to light elements, such as hydrogen and helium. The condensation temperature relates to the change of a substance from gas to liquid form and is influenced by the intermolecular forces present within a substance.

In general, heavier atoms have stronger intermolecular forces due to their larger electron clouds and nucleus, which require more energy to overcome during the phase change from gas to liquid. These forces are indicative of a higher heat of vaporization and fusion, explaining why substances with heavier elements, like metals, have higher condensation temperatures.

Moreover, a substance like silicon has chemical properties that influence its bonding and stability. As silicon is heavier than carbon and hydrogen, it also contributes to a higher condensation temperature for compounds containing it. In contrast, light elements like hydrogen and helium exhibit weaker intermolecular forces, resulting in lower heat of vaporization and fusion, and therefore, attaining a lower condensation temperature.
