Can ice and water be at the same temperature?
The average kinetic energy associated with liquid molecules is the same as the average kinetic energy of solid water molecules. That is how water and ice can be at the same temperature.
At what temperature does water have the same density as ice?

| Ice. Encarta. Redmond, WA: Microsoft, 1997-2000. | “One important property of ice is that it expands upon freezing. At 0° C it has specific gravity 0.9168 as compared to specific gravity 0.9998 of water at the same temperature. As a result, ice floats in water.” |
What happens when ice and water are mixed?
In this case, a mixture of water and ice is created with a temperature of 0 °C. The amount of the melted ice depends on the difference between the supplied heat and the heat used for warming the ice to the melting point. Or else, all of the water freezes which results in a solid state (ice).
Why is ice colder than water at the same temperature?
Answer Expert Verified When ice placed at zero degree Celsius, latent heat absorbed by the ice is greater than the same heat absorbed by the water at same point of temperature that is zero degree Celsius. This is the reason why ice is colder than the water at zero degree.
Is ice always the same temperature?
The temperature of ice varies just like the temperature of any other solid substance–within the physical limitations of its solid state. Just as the temperature of water varies between 32 (degrees) and 212 (degrees) (its freezing and boiling points), the temperature of ice ranges from 32 (degrees) downward.
Is water and ice same density?
Ice is less dense than water Upon freezing, the density of ice decreases by about 9 percent. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
What happens when ice is denser than water?
If ice were more dense than water, it would freeze and sink over and over until the entire lake was frozen. This would eliminate many aquatic organisms and produce a system with far fewer life forms in lakes which freeze periodically.
When ice melts into water its mass increases or decreases?
When ice melts into water its mass neither increases nor decreases i.e it remains the same. This is because it obeys the law of conservation of mass which states that matter can neither be created nor destroyed but it can changed from one form to another.
What happens to the mass of ice when it melts?
No particles are destroyed and none are added. In addition, the size and shape of the particles does not change. Therefore matter, and mass (or weight), is conserved (stays the same) during phase change, contrary to what many students think.
What is the mass of the ice that melts into water?
A 25 g of ice at -20 C is dropped into 50 g of water at 30 C. What is the final temperature of the mixture. Evaluate the final Temperature of the mixture. This is the mass of ice that melts into water. A chunk of 20 g of ice at -25 is put into 100 ml water at 70 C.
What is the mass of the ice at thermodynamic equilibrium?
At the thermodynamic equilibrium, the system is composed of water and ice with the temperature of t m = 0 °C. The mass m m = 1.25 kg of the ice melts.
What happens to the final temperature when two liquids are mixed?
In the case of mixing two liquids in a vessel, a part of the heat is also transferred to the vessel. The final temperature of two bodies will therefore be lower than the theoretically calculated final temperatures due to these (unwanted) heat losses.
What is the final state of the system when ice melts?
The final state of the system depends on how much heat the water supplies. If the amount of supplied heat is larger than the heat necessary for melting all the ice, then the resulting state will be liquid water with a temperature above 0 °C.
