Actually you are wrong, its vise versa, hot water rises and cold water sinks. This is because when water molecules gain energy, they become hot. Molecules try to move away from one another. And this leads to reduction in density. Since density of water reduces as it becomes hot, how water moves up and cold water sinks down.

Is wool warm when wet?
If it is cold water, than it is cold. if it is warm water, it is normal
What are some everyday examples of convection?
When you are boiling water, it's an example of convection because the water at the bottom of the pot gets warm and becomes less dense causing it ti rise to the top and it then makes the cold water warm and the cycle continues. This is known as a convection current.
Does warm water have higher salinity than cold water?
Water salinity describes the amount of salty minerals dissolved in a sample of water. It would therefore make no difference whether the water is warm or cold, since you would have the same amount of salt dissolved in the water per cm3 of water. Salinity would change if you added more water, or if the water was so hot that some of it evaporates, leaving all the dissolved solids behind, but decreasing the amount of water it is dissolved in.
What is the difference between warm water and cold water?
temperature
Does salt or sugar dissolve faster in cold or hot water?
Sugar sinks at the same rate in warm or cold water. Sugar dissolves faster in warm water.
What type of water will things float down faster in warm or cold?
Cold will sink to the bottom. Hot water will rise to the top.
What is the name of the process when warm molecules rise and cold molecules sink?
You are describing convection.
Does a boat sink in hot warm or cold water faster?
It sinks faster in hot water than warm or cold
Do cold dry air masses sink or rise?
cold air sinks as denser - warm air rises
Why doesn't a warm air mass under a cold air mass at a warm front?
Warm air is lighter than cold air, that means that warm air will rise and the cold air will sink.
Convection currents form when warm air rises and cold air sinks What causes the warm air to rise and the cold air to sink?
a difference in density
Convection currents form when warm air rises and cold air sinks. What causes the warm air to rise and the cold air to sink?
a deference in density
Why does cold water sink under warm water?
Because cold water has a higher density than warm water. Water contracts when its temperature lowers, causing its density to increase.
Why do warm air masses rise and cold air masses sink?
Density. You can figure out the details using the ideal gas law.
How would this cold water cause a density current?
Cold water is more dense than warm water so the cold water has to sink to the bottom which causes a density current.
Why does got air rise and cold air sink?
Hot air is lighter while cold air is heavier. This results in warm or hot air rising and cool or cold air falls.
What makes the movement of air?
Differing air temperature causing cold air to sink, and warm air to rise is the main cause of air movement.
