What else can I help you with?
Why is it important to determine the melting ranges of the impure and recrystallized samples of vanillin?
The melting point is an indication of purity.
What is the melting point of billon?
This depends on the chemical composition of the alloy.
Is melting point a physical or chemical?
Physical--- melting something doesn't change its chemical composition.
Why is the melting point of table salt a physical property?
During melting the chemical composition of NaCl is not changed.
What is the melting point of coal?
The melting point of coal can vary depending on the type and composition of the coal. Typically, the melting point of coal ranges from 2100 to 2400 degrees Fahrenheit.
What will be the state of melting point and boiling point of petrol?
Petrol is a complex mixture of hydrocarbons and its composition can vary. Typically, petrol has a low melting point and boiling point range due to its composition of lighter hydrocarbons. The boiling point of petrol is generally around 30-200°C, while the melting point is typically below -50°C.
How do minerals affect a rock's melting point?
Minerals with higher melting points will increase the overall melting point of a rock. Conversely, minerals with lower melting points will decrease the overall melting point. The composition and proportion of minerals in a rock will determine its melting point.
Deffine melting point?
The melting point of a substance is the temperature at which it changes from a solid to a liquid state. It is a characteristic physical property of the substance and can vary depending on its chemical composition and purity.
Why should samples for melting point determination be finely powdered?
Samples should be finely powdered for melting point determination to ensure uniform heating and accurate results. Fine powder allows for even distribution of heat throughout the sample, leading to consistent melting behavior and precise measurement of the melting point. Unevenly sized particles can result in inaccurate readings and can affect the repeatability of the experiment.
What are 5 pysiacal properties?
mass, volume, density, melting point, boiling point
Does sugar affect melting point?
No, sugar does not affect the melting point. The melting point of a substance is determined by its chemical composition and structure. However, adding sugar to a solution can affect its boiling point, but that is a different property.
What is the melting point of 24 gauge galvanized steel?
The melting point of galvanized steel is approximately 2,500°F (1,371°C). However, the melting point can vary depending on the exact composition of the steel and the galvanized coating.
