It depends on how you define "pressure." In general, pressure is the amount of force applied to a particular area. If you are talking about the pressure the water (or any liquid) applies to its container, hot water is indeed "stronger." This is because the molecules of hotter substances move more rapidly, and in all directions - including "outside." (In fact, this rapid movement of molecules is precisely what temperature is.)
On the other hand, if "inner" pressure is what concerns you, cold water (orcold anything) is stronger, for the converse reason - the molecules are moving more slowly and staying more "together." Hence, cold weather is of a higher pressure than hot.
This phenomenon is naturally related to the two other phases of water - if the water becomes cold enough, its molecules more or less stop moving altogether and it freezes into ice (and no situation is of greater pressure than getting frozen!) whereas if it moves rapidly enough, the molecules' bonds will break apart more or less altogether, and it will evaporate into steam (which has enough pressure to power a locomotive piston!).
What else can I help you with?
Does hot water have more pressure than cold water?
What I mean by that is... If you wash your hair with cold water, have you a better chance of rinsing your hair with less limescale than if you used hot water?
What differences are there when you use hot or cold water in a lava lamp?
hot water contains more energy than cold water. cold water causes the water molegules to vibrate more.
Are molecules in hot water different then molecules in cold water?
If you have the same volume of both then there are in cold water more molecules.
Why do you feel more cold after taking a bath with hot water as compared to cold water?
because when you get out of the baths of hot water its a bigger change in temp rather than after you get out of one with a cold water than the temp in te house will be warmer than ur bath
Is hot water less dense than cold water?
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
How much air is in hot water Is there more air in cold water under the same pressure of course?
Colder water can hold more oxygen than warmer water.
Why is the vapor pressure of a warm lake higher than the vapor pressure of a cold lake?
The vapor pressure of a warm lake is higher than that of a cold lake because higher temperatures increase the kinetic energy of water molecules, causing them to evaporate more easily and increase the pressure of water vapor above the lake's surface.
How can the hot water be at a higher pressure than the cold mains in an unvented system?
In an unvented system, hot water can be at a higher pressure than the cold mains due to the presence of a pressure-reducing valve on the cold water supply. This valve controls the pressure of the cold water coming into the system, allowing the pressure of the hot water, which is heated and stored at a higher temperature, to be higher. Additionally, the expansion vessel in the system helps regulate pressure fluctuations by absorbing excess pressure from heating water.
Is warm salt water more dense than cold salt water?
Cold water is more dense.
What is more dense cold water or warm?
cold ocean water is more dense than warm water
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
Does cold air have high or low pressure?
Cold air has a high pressure because it is heavier than warm air.
Cold air exerts more blank than warm air?
air molecules in cold air exert more pressure because they are closer together and collide more often
Is cold ocean water more dense than water water?
more dense
Why does water exert more pressure than air?
Water is more dense than air is.
Does hot water have more pressure than cold water?
What I mean by that is... If you wash your hair with cold water, have you a better chance of rinsing your hair with less limescale than if you used hot water?
Why would hot water pressure be less than cold water?
Hot water pressure may be less than cold water due to the expansion of water molecules when heated, which can create more resistance in the system. Additionally, hot water systems may have buildup of minerals or debris that restrict water flow. Finally, it is possible that the hot water line is further from the water heater, resulting in more friction loss along the way.
