The heat needed to melt one gram of a solid at its melting point is what?
Zarapooh2012
The heat needed to melt one gram of a solid at its melting point depends on the heat of fusion value of the solid. To melt one gram of ice, for example, would require 334 J.

How do you determine heat of fusion?
The latent heat (heat absorbed or released when matter changes to another state) needed to change 1 gram of a substance from the solid phase to the liquid phase withiut changing it's temperature.
What is the melting point of 1 gram of ice?
the melting point of ice is not dependent on its mass, it has a fixed melting point, hundred degree Celsius. The melting point of water (ice) should be zero degrees Celsius or any thing higher, Yes ice would melt a one hundred degrees Celsius but it would also boil at that temperature.
What is the amount of thermal energy that must be added to change ice at the melting point completely into water?
About 333 joules / gram.
If a sample contained 1 gram of pure substance A and another test tube contained 4 grams of pure substance A how would the melting point differ and how would the experiment differ?
The melting point is independent of the quantity. What changes is the amount of heat which must be supplied.
How is stoichiometry used to calculate energy absorbed when a mass of a solid melts?
Grams solid × mol/g × Hfusion
The heat needed to boil away one gram of a liquid at its boiling point is?
The heat needed to melt one gram of a solid at its melting point is the heat of fusion.

A solid substance with a mass of 200 grams is at its melting point temperature in a calorimeter While the substance changes from a solid to a liquid at the same temperature the 400-gram mass of water?
(4.184 J/g*degC)(400g)(40.0*degC-80.0*degC)+(200g)

Would something freeze and melt at the same temperature?
This is a strange question. Water boils usually at 100 degrees Celsius and freezes at 0 degrees Celsius. Who understands this question? I think you mean "If a substance changes from solid to liquid when the temperature exceeds 100 degrees, will it change from liquid back to solid when cooled to below 100?" Yes, it will.

About 333 joules / gram.

What does a gram of air look like?
Gram is a solid measurement. Air is not solid.
What is the difference in crystallization and melting in Geology?
They're the same. latent heat of fusion - heat absorbed by a unit mass of a solid at its melting point in order to convert the solid into a liquid at the same temperature latent heat of solidification - heat liberated by a unit mass of liquid at its freezing point when it solidifies
How is stoichiometry used to calculate energy absorbed when a mass of a solid melts?
Grams solid × mol/g × Hfusion
What is basic difference between melting and fusion?
Melting point is the temperature at which something melts. Like ice has a melting point of 0 Celsius. The heat of fusion is the heat energy that is absorbed (or released) when a substance melts (or freezes) an is measured in energy units, either calories or joules. Ex. One gram of ice must absorb 80 calories of heat energy to change into liquid water.
Are point 20 gram BBs the same as point 2 gram BBs?
yes
