Addition of heat produces more liquid, breaking apart the intermolecular bonds, rather than increasing bond oscillation (increasing temperature).

What is a pure substance that melts at 38 degree Celsius?
Metallic
What happens when a pure substance undergoes a chemical change?
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
Waxy material that melts gradually starting at 52 Celsius and finishes at 65 is it a pure substance mixture?
It's a mix (probably an alloy), a pure substance has a single melting point.
At What temperature does fine silver melt?
Pure silver melts at1763.474 °F.This is equivalent to 961.93 °C.
If 2 pure substances have the same density are they same substance?
No, at a different temperature and pressure the volume of any substance increases or decrease (depending on Temperature and Pressure). Also the severity of the volumetric change depends on the state of the substance. Because density=mass/volume and the volume changes while the mass doesn't the density WILL change slightly in solid phase, noticeably in the liquid phase and significantly in the gas phase regardless of weather or not the substance is pure
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.

If Using density how dowe determine if a substance is pure or not?
If a substance is not pure, the density may, or may not, change, compared to the pure substance.
What does it mean for a substance to be a pure 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.

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.
How do you distinguish a pure substance?
A pure substance will melt over a very narrowtemperature range.An impure substance will melt over a broader, lower temperature range.
What does it mean for a substance to be a pure substances?
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.
What degrees does solid iron melt?
Pure iron melts at a temperature of 2800 degrees, Fahrenheit.
