Do proteins have definite melting points?
Different proteins have different melting points.
Why different fats have different melting points?
different levels of saturation, the more saturated the higher the melting point.
Why does vaseline melt when in heat?
Vaseline is made primarily of hydrocarbons, which have low melting points. When exposed to heat, the hydrocarbons in Vaseline begin to melt and transition from a solid to a liquid state. This process is known as melting point depression, where increased temperature causes the substance to break down and become less structured, leading to its melting.
What is a mixture of hydrocarbons with different boiling points called?
Also a mixture, not a special name.
Why do you think some hydrocarbons are gases and others are liquid?
Different hydrocarbons have different boiling points (and melting points) depending on their molecular size: smaller molecules boil at lower temperatures, larger molecules boil at higher temperatures. This fact is used to refine petroleum by fractional distillation. Methane has very small molecules and is a gas. Gasoline, diesel fuel, and kerosene have medium size molecules and are liquids. Asphalt has large molecules and is solid.
Do proteins have definite melting points?
Different proteins have different melting points.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
Why different fats have different melting points?
different levels of saturation, the more saturated the higher the melting point.
What physical property of hydrocarbons is used for fractional distillation?
If the hydrocarbons are in the liquid state then their differential boiling points are used in separation - fractional distillation. Some hydrocarbons are also separated by their differential solubility in some organic solvents. =)
Do All minerals have the same melting point True of False?
False, all minerals DO NOT have the same melting point

What is the melting point of glue?
There are hundreds of different glues, with different melting points, setting times and means of adhesion.
Do all liquids have the same boiling and melting point?
No, different liquids have different boiling and melting points depending on their chemical composition. The boiling point is the temperature at which a liquid turns into a gas, while the melting point is the temperature at which a solid turns into a liquid. Each liquid has its own unique set of physical properties that determine its specific boiling and melting points.
What is a mixture of hydrocarbons with different boiling points called?
Also a mixture, not a special name.
What causes different melting points?
Different melting points are caused by variations in molecular structures and intermolecular forces between substances. Substances with strong intermolecular forces will have higher melting points, while substances with weaker forces will have lower melting points. Additionally, factors such as molecular weight, shape, and polarity also contribute to the melting point of a substance.
Is there a difference in the melting points of chocolate between different countries in different climates?
Yes, mostly because chocolate can have many different formulations. For example, baking chocolate and milk chocolate have different melting points.
Hydrocarbon boiling points increase the number of carbon or decrease?
Boiling points of hydrocarbons generally increase with an increase in the number of carbon atoms. This is because larger hydrocarbons have stronger London dispersion forces due to increased surface area, which requires more energy to overcome during boiling.
