What are High-Boiling Substances?

High-boiling refers to a substance that has a high boiling point, meaning it requires a relatively high temperature to vaporize or turn into a gas. In general, high-boiling substances are those with a boiling point above 100°C (212°F).

Examples of high-boiling substances include:

1. Water: Water has a boiling point of 100°C (212°F), which is considered a relatively high boiling point compared to other liquids.
2. Oils and fats: Many types of oils and fats have high boiling points, such as coconut oil (176°C/350°F), olive oil (216°C/420°F), and lard (250°C/482°F).
3. Alcohols: Ethanol, isopropyl alcohol, and other types of alcohols have high boiling points, typically between 78°C and 95°C (172°F and 203°F).
4. Glycols: Glycols, such as ethylene glycol and propylene glycol, have high boiling points, typically around 190°C to 200°C (374°F to 400°F).
5. Aromatic compounds: Some aromatic compounds, such as benzene and toluene, have high boiling points, typically between 80°C and 150°C (176°F and 302°F).

High-boiling substances are often used in applications where they need to remain in a liquid state at elevated temperatures, such as in cooking, cleaning, or industrial processes.
