Problem 1: . the melting points of canola oil, corn oil, sunflower oil, and peanut oil are 10°c, –11°c, –17°c, and –2°c. based on this information, how might you separate one type of oil from the rest in a mixture of all four? . a. cooling in a freezer. b. liquid chromatography. c. simple distillation. d. paper chromatography

            One type of Oil (canola oil) can be separated from the mixture by Cooling in a Freezer.

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.

While, simple distillation is not possible because Oils have Smoke point instead of boiling point as at that high temperature oils tend to produce smoke and burns hence, it is not the efficient method.

i look it up online and i'll tell you

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
