Yes, energy has been added
As in the engine? Don't attempt to start it. Water expands when it freezes. If the water in your engine block has frozen there is a good possibility that damage has been done to the block.
An increase in temperature indicates that energy has been added as heat to a system, while a decrease in temperature indicates that energy has been removed as heat. Additionally, changes in volume or pressure can indicate that work has been done on or by the system.
The scientist Mpemba discovered the Mpemba effect, which is the phenomenon where hot water freezes faster than cold water under certain conditions. Despite being initially met with skepticism, the Mpemba effect has been observed and studied in various experiments.
A hypothesis for which freezes the fastest between cold and hot water could be that hot water freezes faster than cold water. This phenomenon, known as the Mpemba effect, has been observed under specific conditions where hot water cools faster than cold water due to factors such as evaporation and convection currents. This hypothesis would need to be tested through controlled experiments to draw a conclusion.
To generate hydroelectricity. But water energy (the potential energy in a head of water) has also been used to turn water wheels for industrial mills and flower mills.
Chlorine and chloramine are both deadly poisons to fish. A water conditioner is usually a liquid that is added to water to remove or nullify the action of chlorine and/or chloramine that has been added by the water authority.
The kinetic energy of the moving water has been transferred to other forms of energy, such as heat and sound, during the stirring process. Once the water stops moving, the kinetic energy has dissipated and the water is now in a state of equilibrium.
It doesn't waste water, but it does waste energy. The water coming out of your faucet is water that has been cleaned and filtered, which requires energy. If you waste that water, you are ultimately wasting energy.
Water seeps down into the earth. As it freezes, it expands. It can crack apart the ground, rocks, or other areas that had been saturated.
yes. it has been proven by people long ago. you might want to try it yourself and put hot water and ice water in your fridge to see which one freezes first!
lightning is actually not matter, but energy. made of static electricity and electrons Lightning is in fact the light/energy given off by air which has been turned into plasma (the fourth state of matter, a cloud of ions and electrons) as it cools back to normal temperature.
No. All the chemical energy has already been extracted from water.
