When water freezes, it will go through an exothermic reaction, which is a chemical reaction that releases energy in the form of light or heat. It is expressed in a chemical equation as:
reactants --> products + energy

How does the volume of a kilogram of water when change when it freezes?
it changes because when it freezes, the molecules within the water slows down thus changing the placement of it, which also changes the over size or volume of water.
When liquid water freezes into ice energy is absorbed or released or not involved?
Energy is released.
Is 32 degrees Fahrenheit the temperature at which water freezes?
Yes, at this temperature the structure the atoms of water are orgainzed in changes, and the state of the substance changes.
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.
Does energy flow into or out of water when it is turning into ice?
It must flow out, ice contains less energy than water. You just have to remember that heat is energy, and all energy, no matter what form, eventually winds up as heat. Take heat energy out of water, it gets cooler, and eventually freezes. Add heat energy to ice, it first changes state to liquid, and then starts to get warmer. Keep adding heat energy to it, it keeps getting warmer and warmer. Keep additing heat energy to it, and eventually it changes state to gas ... called "steam". Take heat energy out of the steam, it first changes state to liquid, then gets cooler. etc. etc.
What change of state and what energy changes occur when water freezes?
the state change is from liquid to solid and the energy change is cold energy to heat energy
How does the volume of a kilogram of water when change when it freezes?
it changes because when it freezes, the molecules within the water slows down thus changing the placement of it, which also changes the over size or volume of water.
How water changes into snow?
it freezes. from the coldness up in the sky
When water freezes has energy been added?
Yes, energy has been added
Is ice wedging chemical weathering?
No, it is physical weathering. Ice wedging occurs when water seeps into cracks in rocks and freezes. Water expands when it freezes, and when that happens it can crack the rock, causing the rock to break down over time. No chemical changes occur during this process. The water stays water, it just changes state, and the rock stays rock, it just breaks down into smaller pieces.
What happens to water when it changes from a liquid to a solid?
A LIQUID FREEZES TO SOLID
What happens to the energy that is lost when water freezes?
It goes to the environment.
How does a solid change from a solid to a liquid?
When water freezes it changes from a liquid to a solid. When water boils or evaporates it changes from a liquid to a gas.
When liquid water freezes into ice energy is absorbed or released or not involved?
Energy is released.
When water freezes it changes from a liquid state to a solid in this process?
yes! exactly.
Describe how temperature changes can make cracks form in rocks?
when water freezes
When water freezes and becomes ice it state of matter changes from a?
splid to a liquid
