How is the melting point of a substance defined?
= temperature at which (all of) a (pure) substance is melting: going from solid into liquid phase.
How can a matter change from solid state to liquid state and reverse the process?
At a unique temperature, called the "freezing point", for each pure substance at a constant pressure, a solid form of the substance can change from solid to liquid phase by absorbing heat energy from its environment without raising the temperature of the substance, and, at the same temperature and pressure, a liquid phase of the same substance, can solidify without changing its temperature if it can transfer heat energy to the external environment.
What is a substance that is malleable and is a solid at room temperature?
How about I tell you what substance is not a solid metal at room temperature. Mercury Everything else is a solid metal at room temperature.
What happens to temperature as solid gold turns to a liquid?
The temperature at which liquid gold solidifies is the same as its melting point, 1064 °C. Generally, the melting point and freezing point for a pure substance are the same. If thermal energy is added to the substance, it will melt. If thermal energy is removed from the substance, it will freeze.
What is the only way the density of a pure substance can change?
By changing the temperature as you can't add anything to a pure substance.
What is the characteristic temperature at which a pure solid changes to a liquid?
The temperature at which a pure solid changes to a liquid is the substance's melting point.
What is the temperature at which a solid changes to a liquid is its what point?
The temperature at which a pure solid changes to a liquid is the substance's melting point.

Is quarts a mixture or a pure substance?
quarts is a solid it is a pure substance and it is a element
What happends at the melting point?
At the melting point a SOLID turns to a LIQUID. (Increasing temperature). At the same temperature , when a liquid turns to solid it is referred to as FREEZING POINT. NB At the boiling point a LIQUID turns to a GAS. (Increasing temperature). At the same temperature , when a gas turns to liquid it is referred to as CONDENSING POINT. NNB Carbon Dioxide, a gas, moves directly to a solid(dry ice) . This is called the SUBLIMATION POINT.

What physical state is silver at melting temperature?
Any pure substance, including silver, at melting temperature can be either liquid, solid, or both. That is the defining characteristic of the melting temperature.
Is iodine a pure substance?
Solid iodine can be found as pure crystals.
