An oil may be converted into a substance that is solid at room temperature by Group of answer choices adding hydrogens, decreasing the number of double bonds in the molecules. cooling it, so that double bonds form and the fats solidify. removing water, causing a dehydration synthesis reaction to occur. removing hydrogens, increasing the number of double bonds in the molecules.

Adding hydrogens, decreasing the number of double bonds in the molecules.

Explanation:

Hydrogen is a catalyst, which means that it accelerates or speeds up the velocity of a chemical reaction, by adding hydrogens to oil it will decrease the number of double bonds in the molecules which will make it solidify over time.

Oil + hydrogen creates substances that are solid at room temperature.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
