Andrei [34K]3 years ago
7 0

Answer:

The presence of an impurity in a substance lowers the melting point, and raises the boiling point of the substance. For example, Impurities present in the water decrease the freezing temperature of the water, and in the same way, impurities increase the boiling point of the water.

kow [346]
The answer to this question would be liquid.

<span>Lipids with high polyunsaturated fatty acid mostly found as a liquid, but the saturated one would be solid at room temperature. A molecule with higher molecular weight will have the higher boiling point and it more likely to be solid at room temperature.
Unsaturated fat is more healthy than saturated fat and it is recommended to reduce saturated fat consumption as it was linked to many diseases.
