this is the absent of water and it is increased in melt point of sugar
Knowing the melting point of a substance provides information to determine what the substance is if its unknown. If you are making a substance, checking the melting point will let you know if you have made what you set out to make, (because impurities can mess up the melting point)
A fast rate of heating can cause the temperature to rise quickly, potentially exceeding the actual melting or boiling point of the substance before it has had time to equilibrate throughout. This can make it seem like the substance has a higher melting or boiling point than it actually does, as it has not fully transitioned to the liquid or gaseous state due to the rapid temperature increase.
Peanut butter is not a pure compound, so it does not have a specific melting point. Cold will make it harder, heat will make it softer, but no specific melting or freezing point. It is a mix of many ingredients, most of which do have specific properties, but when combined in a mix, it is just a sliding scale of consistency.
Glass
what is the melting point of pewter
It doesn't. Melting point is fixed for each substance at a particular pressure. However, very rapid heating can make it difficult to measure the melting point accurately.
Heat it up to above 660.32 °C (melting point)
It is the principal component of glass making
What? That dosent even make any sense... But from what i understand mercury at room temp is liquid so melting point?

Pressure does not change the temperature of rocks, but it does change the melting point. A rock that is under a lot of pressure, even if it is very hot, will stay solid, even if that same rock at the same temperature under lower pressure would be melted. This happens because intense pressure can hold the structure of the minerals together more easily, in a more solid form.So, with an increase in pressure, the melting point of a rock also increases.
resistance means the te power to resist the heat or the electric current/ eg: tungsten which is used to make the filament of the bulb has a high melting point even when it burns on a high temperature so it has a high resistance, whereas in the wire of an electrical fuse has a low melting point as it burns at a high temperature...
