Bot GPT 3.5 The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to atmospheric pressure, causing the liquid to change into a gas. The boiling point of a substance is determined by the strength of the intermolecular forces between its molecules.
Sunflower oil is composed mainly of long-chain fatty acids, such as oleic and linoleic acids. These molecules have strong intermolecular forces, such as van der Waals forces and hydrogen bonding, which require more energy to break in order for the molecules to change into a gas. This results in a higher boiling point for sunflower oil.
On the other hand, water molecules are smaller and simpler, composed of two hydrogen atoms bonded to one oxygen atom. While water does have hydrogen bonding, the intermolecular forces in water are weaker compared to the long-chain fatty acids in sunflower oil. As a result, water has a lower boiling point compared to sunflower oil.
