Answer:
Vegetable oil will dissolve in heptane
Isopropyl alcohol will dissolve in water
Potassium Bromide will dissolve in water
Explanation:
In chemistry, like dissolves like. This implies that polar substances will dissolve in polar solvents and nonpolar substances will dissolve in nonpolar solvents. This is so because, dissolution of a solute in a solvent involves adequate intermolecular interaction between solute and solvent which isn't possible between a polar and a nonpolar substance.
Answer:
The intermolecular forces between the solute and solvent.
Explanation:
When you are heating a solvent, the intermolecular forces are reduced because the distances between molecules are large. Thus, in a solution where solvent is hot the intermolecular forces between solute and solvent are lower than those solutions where solvent is in room temperature.
The covalent bonds do not change because this mean a chemical reaction that doesn't occur in a solution.
Usually solid solutes melts in a higher temperature than boiling point in solvents. Thus, a compound normally doesn't melt in a hot solvent.

Answer:
C is the answer because since it's chemistry particles expanding would most likely be your answer
Dispersion forces or London dispersion forces are collectively referred to as Van der Waals forces. These forces are temporary and arise from the relative position of electrons in one atom to another. If the electrons become distributed in an asymmetrical manner, the negative charge is concentrated at one end of the particle and a positive charge is concentrated at the other. These forces are also called induced dipole-induced dipole attraction.
