What else can I help you with?
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.
How could you use a difference in melting points (freezing points) to separate a solution of two liquids?
freeze one liquid while the other one is still liquidized.
Can you please-Compare the melting points of substances that are gases at room temperature with solids and liquids?
Substances that are gases at room temperature typically have lower melting points than solids and liquids because their intermolecular forces are weaker. Gases have molecules that are further apart, making it easier to overcome these weak forces to change their state. Solids and liquids have stronger intermolecular forces that require more energy to break, resulting in higher melting points.
Do liquids have melting points?
NO!!! However, on change of physical state;- solid to liquid it is 'melting' liquid to solid it is 'freezing' Similarly liquid to gas it is evaporation/boiling gas to liquid it is condensation. Different substances have different temperature for change of physical state. Water being the scientific standard has; - melting/freezing at 0oC boiling/evaporation at 100oC

Why are many organic compounds liquid or gas at room temparature?
Many organic compounds have low melting points and low boiling points. As a result, they are liquids or gases at room temperature.
What is the of evaporation dish?
an open generally shallow concave container for holding liquids for evaporation.
When solids reach their melting points they become what?
When solids reach their melting points, they become liquids. This is the point at which the intermolecular forces holding the solid together are overcome, allowing the particles to move more freely and flow as a liquid.
Which ions have high melting points?
positive ions have high melting points
Do proteins have definite melting points?
Different proteins have different melting points.
When solid changes into liquid?
Solids changing to liquids are melting Liquids changing to solids are freezing Solids changing to gas are subliming Liquids changing to gas are boiling Gases changing to liquids are condensing.
Compared with the melting points of ionic compounds the melting points of molecular solids tend to be .?
Ionic compounds have a higher melting point.
