Answer:
Water molecules tend to stick together due to the structure and charge of the atoms present in the water. Hydrogen atoms are positively charged while oxygen atoms are negatively charged. ... All water molecules are exerting cohesive forces on all the molecules around them including those on the surface of a body of water
Answer:
The force of friction is reduced between the blocks by adding the dishwashing liquid because the liquid is slippery and this makes it difficult for the two surfaces to contact each other directly. Therefore the blocks slip past each other rather than grinding against each other, producing less friction.

With the increase in temperature, solubility of gases in liquid decrease.
Option A
<h3><u>Explanation:</u></h3>
Gases are soluble in liquid but it's solubility depends on temperature and pressure. As the temperature increases, the solubility of gases decrease. It is because with the increase in temperature, the kinetic energy of both the molecules of gas and the solvent increase. This leads to increase in molecular vibration and this makes the gas molecules escape the solution.
This makes the gas solubility vs temperature graph have a hyperbolic curve. As the temperature increases the solubility decrease and vice versa.
