What is a pure substance that melts at 38 degree Celsius?
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.
Waxy material that melts gradually starting at 52 Celsius and finishes at 65 is it a pure substance mixture?
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.
What temperature does every pure substance boil at?
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.
At What temperature does fine silver melt?
Pure silver melts at1763.474 °F.This is equivalent to 961.93 °C.
At what temperature does silver melt in degrees Fahrenheit?
Pure silver melts at 1763.474 °F.This is equivalent to 961.93 °C.
What is the only way the density of a pure substance can change?
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.
When a pure substance is heated or cooled but does not change state the energy as heat is the what?
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 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 is the temperature of a pure solid 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.
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 happens when a pure substances 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

A pure substance boils only at a certain temperature?
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.

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 degrees does solid iron melt?
Pure iron melts at a temperature of 2800 degrees, Fahrenheit.
