Addition of heat produces more liquid, breaking apart the intermolecular bonds, rather than increasing bond oscillation (increasing temperature).
One example of a pure substance that melts at 38 degrees Celsius is naphthalene, a white crystalline solid commonly used in mothballs. When heated to 38 degrees Celsius, naphthalene transitions from a solid to a liquid state.
The waxy material described is a pure substance. It exhibits a melting point range, suggesting a specific compound with a defined melting temperature range, rather than a mixture of multiple substances with varying melting points.
The boiling temperature of a pure substance is unique and specific to that substance. It is determined by its molecular structure and strength of intermolecular forces. This characteristic boiling temperature is referred to as the substance's normal boiling point.
Pure silver melts at1763.474 °F.This is equivalent to 961.93 °C.

The density of a pure substance can change by altering its temperature. As temperature increases, most substances expand and therefore decrease in density, whereas as temperature decreases, most substances contract and increase in density.
The energy as heat is being used to increase or decrease the temperature of the pure substance. This process involves changing the internal energy of the substance without causing a phase transition.
If a substance is not pure, the density may, or may not, change, compared to the pure substance.
The temperature of a pure solid substance remains constant during its phase transition from solid to liquid until all the solid has melted. This temperature is known as the melting point of the substance.
If a pure substance is volatile it means that it vaporizes readily at room temperature. This also means that the substance has weak intermolecular forces.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped

Each liquid boils at a different temperature, but the temperature it boils at is called the Boiling Point. For example, the boiling point of water is 212 Fahrenheit.This specific temprature is dependant on the pressureon the liquid at that time, as an example at ahigher temperatures the boiling point is higher.

The temperature at which a pure solid changes to a liquid is the substance's melting point.
Pure iron melts at a temperature of 2800 degrees, Fahrenheit.
