Obviously frozen water. Its a solid after being frozen so it has become a solid.
Actually it weighs the same I have conducted this experiment for my science fair and found that they weigh the same.

What do the terms ''boiling point'' and freezing point mean?
In physics, "boiling" and "freezing" points generally refer to the temperatre and pressure at which liquid water becomes a gas (the "boiling point"), or when liquid water becomes a soild (the "freezing" point). This can be extended to other compounds as well, although the terms "boiling" and "freezing" are not necessarily used. More correctly, we should describe phase transition points, the temperature and pressure where any compound undergoes a change from one state of matter (eg, solid --> liquid, or liquid --> gas, or gas --> plasma).
Why does water evaporate more easily at the boiling point than at the freezing point?
Because it is closer to its enthalpy of vaporization (ΔvH), at boiling point the liquid molecules have highest kinetic energy so they easily escape from liquid as vapours.
If more than one phase of water is present what does it tell you about the temperature?
The temperature will be either the boiling point (if liquid and vapor is present) or it will be the melting/freezing point (if liquid and ice is present)
Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
raise its freezing point
Is the boiling point of something the same as the melting point?
The boiling point is the temperature at which the vapor pressure of the liquid is equal to the external pressure. It is also the condensation point. The freezing point is the temperature at which liquid and solid coexist in equilibrium. It is also the melting point.
On the basis of its boiling point identify the pure liquid as either ethyl acetate or butyl acetate?
To identify a substance, you must find more than its boiling point. Also look for its freezing point and density.
How is boiling point related to frozen point?
The boiling point and freezing points are simply the temperatures at which a substance changes states from liquid to vapor (boiling) or liquid to solid (freezing). We are going to use water as an example. It is accomplished by adding (boiling) or removing (freezing) sufficient energy in the form of heat to cause a phase change. At 212F (100C) (boiling point) water is at its boiling point. To complete the transition you must add more energy to cause the phase change (the temperature will not change only the water will turn to steam). The heat required to cause the change is called latent heat. It works the same way for freezing except you must remove the latent heat and it happens at 32F (0C).
Does water evaporate quicker with hot or cold water?
Evaporation in water indicates a state change from liquid to gas. Water evaporates much more quickly when it is heated, because as the temperature rises the molecules move around much more quickly and eventually separate themselves from the liquid and mix with the air you breathe. The boiling point is the point where a state change occurs, similar to the freezing point. The state change at the boiling point will be from liquid to gas and the freezing point will be from liquid to solid.
What are some changes in matter?
States of matter are generally described as solid, liquid and gas (although there are more to think about when you really get into science). As such a change in matter is seen to be a change in state; from solid to liquid (melting), from liquid to gas (boiling), from solid to gas (sublimation), from gas to liquid (condensation) and liquid to solid (freezing).Interestingly each chemical has a unique melting/freezing point and boiling/condensation point. We can use those temperatures to help us identify unknown substances.
What is the boiling of of kelvin?
The boiling point is 100 more than the freezing point or 373. Pretty funny!
How do intermolecular forces affect the boiling point of liquid?
the stronger the intermolecular force, the more energy is required to boil the liquid ...
How does the presence of a solute affect the freezing and boiling points of a solvent?
They usually lower freezing points, think antifreeze. And salt water freezes at a lower temp than fresh, that is why they put salt on ice. And they raise boiling points, think salt in water when making spaghetti. Or, again antifreeze.
