Not much at all, and yes, the gold really has no value to be considered financially significant to calculate.

How is argon used in welding?
As an inert gas, it shields the weld from oxygen and corrosion during the melting process. Tig welding means "through inert gas".
Why do different substances require different amount of heat energy during melting?
due to different melting point...
During which change is energy absorbed?
the melting of ice
During which process does water gain the most heat energy?
Evaporation because it requires 2,260 Joules to gain heat energy. Condensation, freezing, and melting require less Joules than evaporation.
What happens during melting evaporation and solidifaction?
i dont know at all
Did the temperature fluctuate while the is melting?
No. The temperature does not change during the melting process. All of the heat energy is used to break the bonds of the solid to form a liquid, i.e. the energy is used in the phase change, and thus is not used to raise the temperature.
What do you do to purify a metal?
You have to get it hot enough where you get to the melting point of the metal. During this melting process the impurities will be removed from the metal and your end result is a purer metal.
When you heat ice on a hot stove the ice melts. What is happening during this process?
During the melting process, the heat is being used to break apart the bonds holding the solid ice together. None of the heat goes into changing the temperature, as it all goes into the phase change. So, during the actual melting process, the temperature does NOT change.
Why does temperature does not rise during the process of boiling and melting though heat energy is constantly supplied?
you must have observed during the experiment of melting that the temperature of the system does not change after the melting point is reached till all the ice melts this happens even though we continue to heat the breaker that is we continue to supply heat
What is the process when a substance is transformed from a solid into a liquid?
This physical phenomenon (a change of phase) is called melting; during melting the chemical nature of molecules is not changed but the bonds between molecules are weakened.
Is silver clay cheaper than sterling silver?
On the contrary, silver clay is more expensive than sterling silver. The clay is a special compound containing silver plus special adhesives that are burnt out during the firing process.
What occurs during both melting and freezing?
During both freezing and melting, you have a phase change.
How is melting similar to evaporation?
Melting and evaporating are both a change in matter.also during evaporation and melting there is no change in temperature
How is argon used in welding?
As an inert gas, it shields the weld from oxygen and corrosion during the melting process. Tig welding means "through inert gas".
What happens when the temperature stays the same in a melting curve?
During melting the temperature remain constant if it was achieved the melting point.
A change of what occurs during both freezing and melting?
A change of solid occurs during both freezing and melting.
What do melting and evaporation have in common?
melting and evaporating are both a change in matter. also during evaporation and melting there is no change in temperature. melting and evaporating are both a change in matter. also during evaporation and melting there is no change in temperature.
