If you've noticed, when you turn the shower on the morning, the cold water comes through from the pipe first and it will splash and sound different against the bottom of the shower compared with when the hot water, which comes along shortly afterwards, comes in; the note will change. This is a real observation; your ears aren't deceiving you.
The reason for it is that water changes its viscosity - its stickiness - according to its temperature.
If you could zoom in with a really powerful microscope and look at some water molecules, what you'd see is they are shaped like miniature boomerangs. At the apex of the boomerang you would see an oxygen atom and on each of the arms, you'd see hydrogen atoms.
Oxygen loves electrons, so it pulls the electrons of itself and the hydrogen towards itself very tightly, and that makes the oxygen a bit minus. The hydrogens are correspondingly therefore a bit plus.
As a result, when water molecules are sitting together side by side in solution, the positively charged hydrogens are attracted to the negatively charged oxygens of an adjacent molecule and this is called hydrogen bonding. It makes water sticky, and it gives it some of its special properties that in fact help it to make life happen on Earth. So it's pretty important that this happens.
But, when you heat the water up, the particles start to move much more quickly. They have more kinetic energy which is a function of the temperature. This means that they're zipping past each other much faster. They're therefore gluing onto each other less well and this makes the water runnier or less viscous.
So when it comes splashing out of the shower and hits the shower pan, the water fragments into smaller particles and makes a higher pitched splashing noise than when it goes into the cup or goes into the sink when it's cold.
Have a listen next time you're in the bath for the shower and you will see that the note is different.
Water can be either hot or cold depending on the temperature. Water at room temperature is considered neither hot nor cold.
Tepid water is between hot and cold.
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.
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.
The hypothesis of mixing hot and cold water is that the resulting water will reach a temperature that is the average of the initial temperatures of the hot and cold water. This is based on the principle of thermal equilibrium, where heat will transfer from the hotter water to the colder water until they reach a common temperature.
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.
The difference in taste between hot and cold water is due to temperature affecting our taste buds and the solubility of substances in water. Hot water can enhance the release of flavors and aromas from substances in the water, making it taste different than cold water.
hot because when its cold it turn hot
No hot water freezes, it has to cool off first.
No, cold water is not hot. Cold water is at a lower temperature than hot water.
If you have the same volume of both then there are in cold water more molecules.
Water can be either hot or cold depending on the temperature. Water at room temperature is considered neither hot nor cold.
To adjust the temperature of the water coming out of the hot and cold water tap, you can turn the handles on the tap. Turning the handle towards the hot side will increase the temperature, while turning it towards the cold side will decrease the temperature. Experiment with different combinations of hot and cold to find the desired temperature.
In hot Weather
Yes, hot and cold water can mix with food coloring when hot water rises to the top if there is sufficient turbulence or agitation to mix the colors together. The movement and flow of water can help distribute the food coloring throughout the container, allowing for mixing between different temperature layers.
