Why upthrust force is higher in hot water than cold water?
Hot water is less dense than cold water because the increased temperature causes the water molecules to expand and spread out. As a result, the same volume of hot water displaces a larger mass of surrounding water, creating a stronger upthrust force due to the greater difference in density.
How does hot and cold water separate?
Hot and cold water can separate due to differences in their temperature and density. When hot and cold water are combined, the hot water tends to rise to the top because it is less dense than the colder water below. This process is known as thermal stratification.
How does the movement of water change in a hot cup and cold cup?
In a hot cup, water molecules have more energy, so they move faster and further apart, leading to expansion and lower density. In a cold cup, water molecules move slower and closer together, resulting in contraction and higher density. This difference in movement affects the overall behavior and properties of the water in each cup.
Why does cold air have a higher density than warm air?
Cold air is denser than warm air because the molecules in cold air are closer together, leading to a higher mass per unit volume. When air is heated, the molecules gain kinetic energy and move farther apart, resulting in lower density.
Why does hot water float above cold?
In hot water the molecules vibrate faster than cold, resulting in the same number of molecules taking up a larger space. This means that hot water is less dense than cold water, and thus floats above the cold water.
How can hot water flaot on cold water?
hot water has a lower density because since it is hot, all the particles repel from each other. therefore, cold water has a greater density that hot water which results in the floating effect
How density and temperature of air related?
cold air has higher density, by hot air is opposite
What has a higher rate of evaporation hot water or cold water?
A higher rate of evaporation has hot water.
What floats more between cold water and hot water?
The density of cold water is greater than hot water so there will be more substances that will float in it.
If cold water is denser than hot water then how can you float in a warm water?
The difference in water density (hot-cold) is very small, compared to the difference in density between water of any temperature, and your body. That is, even hot water is more dense that we are, so we still float.
Is pure ammonia soluble in hot or cold water?
Ammonia is soluble in both hot and cold water, with a higher solubility in cold water.

Dose cold water weigh from hot water?
Cold water is weigh from hot water; as the molecules tend to free (or expand) by getting heat, which causes increase in specific volume (i.e. decrease in density). As a result, hot water becomes lighter, compared to cold.
Which weighs more cold water or warm water?
If you think to density (not weight) hot water is less dense.
Will things sink faster in cold or hot water?
Cold water has a higher density than that of warm water (hence it is lower than the warmer parts of water in the same container). Due to its increased density, the same sinking object will descend more slowly through its warmer comparison.A2. The last part should read ".. than through its warmer .."And in this type of question, you should consider viscosity as well. not much different in hot or cold water, but very different in oil or treacle with temperature change.
