Ice at 0°C has less energy than water at 0°C. This has to do with the forces between molecules - in other words, there is potential energy involved. To freeze the water, this excess energy has to go somewhere - ergo, it has to be removed.

What happens if energy is added or removed from a glass of ice water?
for a liquid to freeze , the attraction between the particles must overcome the motion of the particles.
How do you get the energy released when 150 grams of water freezes?
You need to get the energy OUT of the water; otherwise it won't freeze. This is usually done by putting the water in contact with something colder.
What happens if you add or remove energy to a glass of water?
if you add it will stay liquid but if you remove it will freeze
How do you change solid water to liquid and liquid water to gas?
You can change both of these by increasing or decreasing the speed of the molecules (kinetic energy), or by increasing or decreasing the heat applied (thermal energy). If you want to melt ice, you can increase the kinetic energy by increasing the thermal energy. The opposite occurs if you want to freeze water.
Why cant liquid water at 273.3 k will not freeze in terms of gibbs energy?
Water cannot freeze at 273.3 k in terms of gibbs energy because when absolute zero (Which is 273.3 k or 0 celcius) is achieved than the water will be at equilibrium, which means that the water melts at the exact same rate the water freezes. Absolute zero has not been achieved, so there is no example of this.
What happens if energy is added to or remove from a glass of water?
If a sufficient amount of energy is added to a glass of ice water, the ice will melt, and if a sufficient amount of energy is removed, the water will freeze solid.
What happens if energy is added or removed from a glass of ice water?
for a liquid to freeze , the attraction between the particles must overcome the motion of the particles.
What freezes faster sugar water or salt water or water?
Assuming you had equal amounts of each, the pure water would freeze first...Adding sugar or salt to water lowers its freezing point, meaning that more energy would be required to be removed from salt water and sugar water to freeze it
What freezes faster warm water or cold water?
Cold water, less energy must be removed from cold water to make it freeze. warm water has more energy which needs to be removed before it freezes. it is an urban myth that warm water freezes faster.
What energy transfers are there when water freeze?
Heat
What happens when heat is removed from a system?
The water gets colder. If enough heat is removed, including the heat of fusion, the water will freeze. Removing the heat of fusion does not change the water's temperature.
Does water require energy?
If you take energy in the form of heat, from water it will freeze and so is not water any more.
Why does hot water freeze faster that cold water?
Kinetic energy
What happens to particles in ater when you freeze them?
Lol, if you mean water then the following is whats going on: freezing a particle involves removing energy, and when energy is removed the molecules in the water slow their vibrations. So Basically the particles slow down because the freezing or the water has drained a sufficient amount of kinetic and potential energy.
Why moving water does not freeze?
beacuse the molecuels in moving water are have more kinetic energy and they moves randomly in all direction hence it can't freeze
If water had a lower specific heat capacity would lakes be more likely or less likely to freeze in winter?
More likely; a lower heat capacity means that less energy must be transferred to result in a temperature change. If less energy needs to be removed then it is easier for the surroundings to absorb it and make the lakes freeze.
What Energy is released when carbon dioxide is removed from?
water
