Question

The melting points of canola oil, corn oil, sunflower oil, and peanut oil are 10° C, -11° C, -17° C, and -2° C, If you cool a mixture of these oils to 5°C, which one can you separate easily?

a. corn oil
b. canola oil
c. peanut oil
d. sunflower oil

Answer 1

Canola Oil

Step-by-step explanation:

The data given is as;

Oil Melting Point / Freezing Point

Canola Oil 10 °C

Corn Oil -11 °C

Sunflower Oil -17 °C

Peanut Oil -2 °C

When the mixture of these oils is cooled to 5 °C only the Canola oil will solidify because it has a melting point of 10 °C and exists in solid state below 10 °C (Freezing Point). Therefore, it can easily be separated from remaining mixture which is present in liquid state.
