Argon's low melting point is due to its weak van der Waals forces between atoms, as it is a noble gas with a monatomic structure. These weak forces require less energy to overcome, resulting in a lower melting point compared to other elements with stronger bonds.

Is it true that it takes a lot of heat to melt a substance with a low melting point?
No, substances with low melting points require less heat to melt compared to those with high melting points. This is because low melting point substances have weaker intermolecular forces holding their particles together, so they can be easily broken with less energy input.
What is considered a high melting point and what is considered a low melting point?
resistance means the te power to resist the heat or the electric current/ eg: tungsten which is used to make the filament of the bulb has a high melting point even when it burns on a high temperature so it has a high resistance, whereas in the wire of an electrical fuse has a low melting point as it burns at a high temperature...
What molecules are widely separated so the gas has a low melting point?
In gases, molecules are widely separated so the gas has a low melting point. The lower melting point is due to the weak intermolecular forces between the molecules, allowing them to move freely and not be held together tightly. Examples of such gases include helium and neon.
Is 115 high for a melting point?
Not necessarily. The melting point of a substance can vary widely, so 115 degrees Celsius could be high or low depending on the specific substance in question. It's best to compare the melting point to known values for the substance to determine if 115 degrees is considered high.
What is its melting point when the freezing point of a substance is 68C?
The freezing point is 680C
Which mealting point is higher neons or silicons?
At STP, neon is a gas, so its melting point is low whereas silicon is a solid, so its melting point is high

Does silicon have a high or low melting point?
High because you make cakes with it so it wont melt

Why do nonmetallic elements have low melting points?
Monatomic substances have a low melting point an boiling point because they are held together by van der Walls forces which are very weak electrostatic attractions so less energy is needed to break them apart resulting in a lower boiling and melting point.
Does peanut butter have a high melting point or a low melting point?
Peanut butter is not a pure compound, so it does not have a specific melting point. Cold will make it harder, heat will make it softer, but no specific melting or freezing point. It is a mix of many ingredients, most of which do have specific properties, but when combined in a mix, it is just a sliding scale of consistency.
Do solids have a low melting point?
Some do while others do not. To be solid a substance must merely have a melting point that is above room temperature. Gallium has a melting point just above room temperature, so it is normally solid but it will melt in the palm of your hand. By contrast Tungsten has such a high melting point that not even the hottest lava from Earth's volcanoes can come close to melting it.

Does uranium have a high or low melting point?
Uranium has a high melting point of 2,075°C (3,767°F), which is relatively high compared to many other metals. This high melting point makes uranium suitable for use in nuclear power reactors, where it needs to withstand high temperatures.
Why does solder need to have a low melting point?
Solder needs to have a low melting point so that it can be easily melted and flow into the joint being soldered without causing damage to the components being soldered. If the melting point is too high, there is a risk of overheating the components and causing them to malfunction or become damaged.
Which element has a low melting point and boiling point?
The element with the lowest melting and boiling point is helium. Helium is a noble gas with an atomic number of 2 and a very low atomic mass, which contributes to its low melting and boiling points. At standard pressure, helium has a melting point of -272.2 degrees Celsius and a boiling point of -268.9 degrees Celsius.
