When water is warmed, its molecules gain kinetic energy and start to move more rapidly. This increased movement causes the molecules to spread apart, resulting in a decrease in density. As a result, warmer water tends to rise above cooler water, which can influence circulation patterns in bodies of water. The overall effect is that the physical properties of water, such as viscosity and surface tension, are altered as temperature increases.
When water is warmed, its molecules gain energy and move faster, causing the water to expand and become less dense. This is why warm water rises in colder, denser water. Heating water can also lead to evaporation, where some of the water molecules break free from the liquid state and become a gas.
The water molecules remain unchanged.
the bonds between the water molecules are broken
Whe you boil water, molecules of water "escape" into the atmosphere. The molecular structure of water is unaffected by boiling.
When granulated sugar and water come in contact, the water molecules surround the individual sugar molecules, and the sugar molecules go into solution. You end up with an aqueous solution of sugar.
the molecules separate more

When water is warmed, its molecules gain energy and the temperature of the water increases. This causes the water molecules to move faster and further apart, leading to expansion in volume. If the temperature increase is sufficient, the water may reach its boiling point and transition into a gas (steam).

The liquid molecules are transformed in gas molecules.
The warmed water next to a heater rises due to decreased density, creating a convection current. This movement helps distribute heat more evenly throughout the water.
Happens a lot.
When water is warmed by the sun, the water molecules absorb the sun's energy and gain kinetic energy, causing the water temperature to increase. This process does not produce anything new, it simply increases the thermal energy of the water.
The liquid molecules are transformed in gas molecules.
The sugar will dissolve in water because sugar is polar and so is water with hydrogen bonds. When attraction happens, the water molecules will separate the sugar molecules and the sugar will be dissolved.
