they are the same... dont know who wrote this but it can be the same such as dry ice, or different such as water. however boiling point will sometimes be higher than melting point
The boiling point of an element is often higher than its melting point because it takes more energy to separate the molecules in a liquid and turn them into a gas. In the case of potassium, the boiling point is higher than the melting point because the forces holding the potassium atoms together in a liquid state are stronger than in a solid state.
The boiling point is lower than the melting point because during boiling, the intermolecular forces holding the molecules together are overcome, allowing them to escape into the gas phase. In contrast, during melting, the intermolecular forces are still present but being overcome to transition from solid to liquid.
An impure sample will have a lower melting point, and will also have wider melting point range than that of a pure sample of the same substance. a sharp melting point range can also indicate a eutectic mixture
Chlorine has a higher boiling point than oxygen. Chlorine's boiling point is -34.6 degrees Celsius, while oxygen's boiling point is -183 degrees Celsius.
The boiling point as stated is 59C, the melting point is -7C, so at 21C it is at a higher temperature than the melting point but lower than the boiling point, so hence is in a liquid state ( at 59C or higher it would be converted to gas, at -7C or lower it would solidify ).
The boiling point is always higher than the melting point.
The melting point is higher than the boiling point of Arsenic only because the melting point is when Arsenic is under pressure because otherwise it would sublimate, or turn directly from a solid to a gas, a the "boiling" point of 614 degrees Celsius and normal atmospheric pressures.
Yes.
Water has a high melting point and boiling point because of hydrogen bonds
well acuttaly a boiling point is higher because the boiling point is at 100 degrees and like so a melting point is a 0 degrees and a boiling point the particles spread out quicker but the melting point the particles are a strong bond so cannot be squahsed and are at a lower rate of temprrature/heat
No. The boiling point is higher temp. than the melting point. When something is melted, it becomes liquid: when something is boiled, it begins to become vapor.
No, boiling points are always higher than melting points. When you turn a solid to a liquid, this process is called melting, and requires a lower temperature than boiling the substance. Take ice water for example. Ice becomes pure water at 0oC. The temperature needed to boil pure water is 100oC, which is a bigger number than zero.
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
No, LiCl (Lithium chloride) will not have a higher boiling point than water. The boiling point of water is 100 degrees Celsius, whereas the boiling point of LiCl is significantly higher at 1382 degrees Celsius.
A fast rate of heating can cause the temperature to rise quickly, potentially exceeding the actual melting or boiling point of the substance before it has had time to equilibrate throughout. This can make it seem like the substance has a higher melting or boiling point than it actually does, as it has not fully transitioned to the liquid or gaseous state due to the rapid temperature increase.
The boiling point of an element is often higher than its melting point because it takes more energy to separate the molecules in a liquid and turn them into a gas. In the case of potassium, the boiling point is higher than the melting point because the forces holding the potassium atoms together in a liquid state are stronger than in a solid state.
yes, for the same molecule. However, some substances don't have a liquid phase and so the melting point is exactly the same as the boiling point at normal pressures (sublimation is the phase change from solid -> gas)
