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.
What is the definition of fusion?
The act or operation of melting or rendering fluid by heat; the act of melting together; as, the fusion of metals. 2. The state of being melted or dissolved by heat; a state of fluidity or flowing in consequence of heat; as, metals in fusion. 3. The union or blending together of things, as, melted together. The universal fusion of races, languages, and customs . . . had produced a corresponding fusion of creeds. C. Kingsley. Watery fusion (Chem.) the melting of certain crystals by heat in their own water of crystallization. 4. (Biol.) The union, or binding together, of adjacent parts or tissues.
What is used in energy calculations involving a substance being melted or frozen?
q=mHf and q=mHv in both where q= heat( in joules) m= mass Hf = heat of fusion, which is 334J/g Hv= 2260J/g
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.
Is melted copper a mineral why or why not?
is melted copper still a mineral
Would the computed Latent heat of fusion be affected if the ice in the inner cup is not totally melted when the final temperature is determined?
yes. because the temperature will change. thus, increasing ur error.

What is Lack of fusion of weld fault?
It's when the different metals parts haven't melted together properly

What is it called when new nuclear membranes form?
After the triple cores melted during nuclear fusion
Is it true that when ice-cubes melt it absorbs energy?
The molecules in an ice cube arrange themselves so the mutual forces of attraction between the molecules is stronger then they are in liquid form. These forces can be overcome by adding energy to the ice cube, which starts the molecules jiggling until they break free. When they break free you have water. So energy isn't released by a melting ice cube, it is absorbed. The amount of energy that must be absorbed to just melt the ice (overcome those strong attractive forces), without raising the temperature is called the "latent heat of fusion". Every solid that can be melted to a liquid form has a "latent heat of fusion". This is a number you can look up and is different for different substances. In the reverse situation, when water turns to ice, the water releases energy (latent heat of fusion again)and the molecules slow down enough to be captured by the stronger forces. In the South, when a freeze is coming, the farmers will spray their crops with water because before it can turn to ice it first releases the latent heat of fusion energy. This will keep the crops slightly above freezing for a little longer then without the water spray and they hope its long enough.
How can define fusion regarding welding?
Fusion is the melting and mixture of base metal to the melted filler material (Rod or Electrode). It takes place in the puddle and is the Weld. Sorta like making mud by adding water to dirt. If they don't mix there is no mud.
Was the Chernobyl meltdown from fusion or fission?
The reactor(s) at Chernobyl are fission reactors, and fission of fuel and fission products following the fire and the overheating of the core melted it down.
Is melting a warming process?
Generally melting is a warming process because whatever is being melted absorbs latent heat to change states from solid to liquid or liquid to gas. An exact figure can't be given because the amount of latent heat depends not only on the substance but also on the pressure. The latent heat required to melt ice to water is ABOUT 336kj/kg (kilojoules per kilogram). There are exceptions such as gases and liquids at the what is called the critical point or triple point.No!!!!
How much heat is required to convert 0.3 kilograms?
That's going to depend on a lot of things that you haven't told us, such as -- what the 300 grams are made of (This will tell us the melting and boiling temperatures of the substance, as well as its latent heats of fusion and vaporization, and its specific heat capacity. We'll need to know all that stuff to give you an answer) -- what you want to convert them from and to -- what their temperature is when you start the process
The number of grams of ice that can be melted by 1 g of 100 c steam is?
- 80 calories are needed to melt 1 gram of 0°C ice to 1 gram of 0°C water - 640 calories are released when 1 gram of steam at 100°C is condensed to water at 0°C - 80/640 or 1/8 gram of steam at 100°C must be condensed
