What liquid melts slower than water?
The rate of melting of a solid is determined by (1) the difference between the melting point of the liquid and the temperature of the heat source providing the energy for melting, (2) the heat conductivities of the solid and liquid forms of the substance being melted, and (3) the heat of fusion of the substance being melted. If these factors are kept constant, any liquid will melt as the same speed. In practice, under common conditions, water melts more slowly than most other substances, because it has a very high heat of fusion.
What is the meaning of fusion?
The act or operation of melting or rendering fluid by heat; the act of melting together; as, the fusion of metals., The state of being melted or dissolved by heat; a state of fluidity or flowing in consequence of heat; as, metals in fusion., The union or blending together of things, as, melted together., The union, or binding together, of adjacent parts or tissues.
Since the melting and freezing temperature are the same does something stay the same temperature when it is melting?
When a substance is melting, it stays at a constant temperature until all of it has melted. During this process, the energy being added is used to break the intermolecular forces holding the solid structure together, rather than raising the temperature. Therefore, the temperature remains constant until the phase change is complete.
Is melting of ice cream physical or chemical change?
The melting of ice cream is a physical change. It involves a phase change from solid to liquid, without any new substances being formed. The chemical composition of the ice cream remains the same before and after melting.
Does the melting point of aluminum change with the thickness?
The melting point of any given substance (such as aluminum) has nothing to do with the thickness or shape of the material being melted. It will melt at the same temperature. But it does require more heat in order to heat a thicker piece of aluminum to its melting point.

Does sand affect melting points?
Sand does not affect the melting point of a substance since it does not mix with the substance during the melting process. Sand is typically heated separately and can act as a heating medium but does not directly influence the melting point of the substance being melted.

How do use the word solidified in a sentence?
wax got solidified as soon as it cooled after melting

What is the melting point of emerald?
Emeralds, being a variety of beryl, do not have a specific melting point like metals or other crystalline substances because they are not typically melted in a traditional sense due to their complex structure. Instead, when subjected to high temperatures, they may break down or decompose rather than melt uniformly. However, beryl generally starts to lose its structural integrity at temperatures around 1,000 to 1,200 degrees Celsius (1,832 to 2,192 degrees Fahrenheit).
Can you melt powders into liquids?
Definitely. Powders are simply solids broken into smaller particles. As we know, melting is the phase change from the solid state to the liquid state. Thus, we can definitely melt powders.
Why does solder need to have a low melting point?
Solder needs to have a low melting point so that it can be easily melted and flow into the joint being soldered without causing damage to the components being soldered. If the melting point is too high, there is a risk of overheating the components and causing them to malfunction or become damaged.
What does the flat portion of the temperature time graph in the experiment of melting point indicates?
The flat portion of the temperature-time graph during the melting point experiment indicates that the substance is undergoing a phase change. As heat is being absorbed to break the intermolecular bonds and transform the solid into a liquid, the temperature remains constant until all of the substance has melted.
Is there bacteria in chocolate that is melted due to heat from being in a car?
Bacteria can be present in chocolate, but melting it due to heat in a car does not create new bacteria. However, if the melted chocolate is exposed to contaminants in the environment, bacteria could potentially grow. It is always best to store chocolate in a cool, dry place to prevent bacterial growth.
