Melting point of the substance
It is physical change. It is a physical property. There is no change in the composition of the was as it becomes liquid.
Water: it will change from ice when melted. Metals and rocks, when exposed to enough heat, will melt into liquids.
if a 50 g of iron gets melted how much liquid does it produce
No. Solid gold is denser than liquid gold and so it will sink. This is true of almost every substance except water.
They are mixtures.
When a solid turns into a liquid, the substance has melted.
It is physical change. It is a physical property. There is no change in the composition of the was as it becomes liquid.
If an ionic substance were melted, it would become a liquid made of ions; in this case the label "ionic liquid" could be applied.
Water: it will change from ice when melted. Metals and rocks, when exposed to enough heat, will melt into liquids.
electrolytes
Yes. "Molten" means the compound has melted into the liquid state. Anything that heat has melted into a liquid can be described as molten.
No
The ice melted into a liquid form.
if a 50 g of iron gets melted how much liquid does it produce
Melted ice is liquid water and water boil.
No. Solid gold is denser than liquid gold and so it will sink. This is true of almost every substance except water.
for example ice is melted down into a liquid
