Answer:
Elements are types of atoms that have a unique number of protons. In fact, from left to right, the periodic table is arranged by the number of protons that each element contains. oms make up matter. An atom is the smallest unit of matter that retains all of the chemical properties of an element.

Explanation:
Adhesion means the ability to stick on the surface of another substance.
Water exhibits adhesive forces due to which it is able to stick to the glass. Due to adhesive forces water spreads over the surface of glass and sticks to it.
These adhesive forces between the glass and water enough that it deforms the spherical shape of water molecules and help them stick to the surface of glass. As a result, adhesive forces overcome the repulsion between like molecules.
Hence, water is able to “stick” to the side of glass due to strong adhesive forces.
The enthalpy of formation of CF

<h3>What is enthalpy ?</h3>
A thermodynamic system's enthalpy H is calculated by multiplying its internal energy by the product of its pressure and volume. In the equation H = U + pV, U stands for internal energy, p for pressure, and V for system volume; pV is also frequently referred to as the pressure energy P.
The amount of heat in a system under constant pressure is measured as enthalpy (H). Chemists frequently gauge how the enthalpy of chemical systems changes when reactants transform into products. The enthalpy change, which is the same thing as the heat that is absorbed or released by a process at constant pressure, is denoted by the letter H.

In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory.
so the third one should be correct.
Answer:
Image result for How do solute concentrations affect the rate of osmosis within the cell?
Concentration gradient - The movement of osmosis is affected by the concentration gradient; the lower the concentration of the solute within a solvent, the faster osmosis will occur in that solvent.
I think this is it^^^
