No, if you melt a coin it is still the same mass just in a different form.

Does the melting point and freexing point change depending on the mass?
No; melting/freezing points do not change as a function of mass, as long as the mass maintains constant composition.
when petrol burns in air is its mass increased or decreased?
increast
How is he melting curve of duplex DNA affected by adding a small amount of ethanol?
If a DNA strand is denatured, it is generally as a result of an increase in temperature. If monitored, the absorbance can be graphed as a function of temperature. The midpoint in the resulting curve is the melting point. The melting curve can be altered by decreasing the ionic concentration, causing an decrease in the melting temperature. This is due to the Poly-anion nature of the DNA helix. When the ionic strength is decreased, the stability of the DNA strand decreases. When a small amount of ethanol is added, the non-polar effect has the biggest impact. When EtOH is added, the non-polar nature of the solution is decreased, resulting in a decreased importance of the hydrophobic forces on the stability of the helix, resulting in a lower melting temperature.
What physical property is identical for the two isomers co C4H10?
The melting and boiling points are different. Butane has a melting point of 135.4K and 2-methylpropane [isobutane] has a melting point of 114K. The boiling point of Butane is 272.6K and isobutane @ 261K. It has to do with there structures. J
How can you determined that a coin is not pure silver if you know the mass and the volume of the coin?
By knowing that the coin would be affected by m leave it on water easuring the changes if you

What does aging do to a coin's mass?
When a coin ages it lowers the mass of a coin because usually some of the metal such as copper on a penny comes off the coin leaving it with a lighter mass then it started off with.
What happens to acceleration when mass is increased?
it gets decreased

What is melting point of coins?
This can't be answered. It depends what the coin is made of.
