Question

Why do oils remain in a liquid state even in winters?

Answer 1

Oils remain liquid In winters because:

• Oils have low melting points
• Various fatty acids are also present and they remain in a liquid state even in winter.
• Oil is denser than water.
• Vegetable oil consists of molecules in long chains called lipids, usually with a mixture of molecules of different sizes and shapes.
• That makes it hard for the oil to form a regular crystal, suppressing ordinary freezing.
• In oil, the intermolecular force is less as they have a low melting point.

Hence oil remains a liquid state in winter.
