The water has intermolecular forces that holds the liquid together.?
These forces are from the hydrogen bonding between Hydrogen and Oxygen.?
Hot and Cold are terms that describe relative heat and energy within a substance. Under high heat and high kinetic energy within the molecules, the substance is referred to as hot.
The kinetic energy within substances can break the intermolecular Hydrogen Bonds.
Water also bonds with the hull of a boat but when heat is available to keep the water moving, the length of time that the water stays bonded to the hull is reduced.?
In Hot water, the hull of the boat is bonded and held back by the water for a shorter amount of time while in cold water, the bonds between the water molecules are stronger. The stronger cold water molecules stay bonded longer and with stronger bonds. When a boat cuts through the water, it needs to break the hydrogen bonds within the cold water but the bonds in cold water are much stronger than in hot water.
The boat must expend kinetic energy to break the bonds. So the energy to move the boat is spent on breaking the bonds rather than moving the boat forward.?
The difference between hot and cold water is minimal.
A boat will typically go faster in cold water because cold water is denser than hot water, which reduces drag and allows the boat to move more efficiently through the water. Additionally, colder water can improve engine performance and result in higher speeds for the boat.
A boat will sink at the same rate regardless of the water temperature. The sinking rate is primarily determined by the density of the water and the weight of the boat.
It sinks faster in hot water than warm or cold
Quite high regardy such things like the tempetature of the or where the boat was. If it was a cold water and the water was cold hympohermia could kick in. But your chances are high if survival
No.
Yes, cold water can dissolve substances, but generally at a slower rate compared to hot water. The speed of dissolution will vary depending on factors such as the solubility of the substance and the temperature of the water.

noting it works (in the science meaning; to cause a change) a lot.
If the water is cold, that means that water molecules have small speed, in hot water, molecules have greater speed, thus greater energy, and need less energy than cold water to be kicked out through the surface.
Cold water and hot water have different densities due to their different temperatures. When they are mixed together, the hot water rises and the cold water sinks, creating layers instead of being thoroughly mixed. This phenomenon is known as thermal stratification.
There is no difference on how well a toy boat will float in water depending upon the temperature. The ability for an object to float is if it can displace more than its own weight in water, which doesn't depend on the temperature of the water.
