Anything with a covalent bond has a relatively low boiling point because they intermolecular forces are weak. On the other hand ALOT of energy is required to melt ionic compounds

What are some characteristics of polymers?
Generally: - they have a low thermal and electrical conductivity; - their deformation is very temperature dependent; - low Young module (they deform a lot for low tensions/strenghts); - the atoms are bond by covalent and secondary bonds (Van der Walls and hydrogen bonds)
Water does not behave ideally at 273k why?
gases behave ideally at high temperature and low pressure at 273kthe temperature in celcius is o degree which is a very low temperature and atlow temperature forces of attraction becomes significant so they behave non ideally
Why does metallic bonds have a high melting point?
Most metals do indeed have high melting points . The simple explanation is that the metallic bonds in these metals are very strong. There are low melting metals, the lowest mp metals are mercury a liquid at room temperature, gallium that melting at around 300C.
Does ionic bonds have high or low resistance?
High. Second only to covelant bonds.
What makes metallic bonds unique?
Metallic bonds are unique because of its ability to conduct electricity. They also have a low electronegativity and a low ionization energy.
What is the principle of liquation?
Liquation is the process of using controlled heat to separate a metal that melts at a relatively low temperature from a metal that melts at a higher temperature.
Does the temperature of a room affect how fast a candle melts?
The room temperature is too low for an effect.
Why does chocolate melt faster under heat?
Chocolate melts because of the temperature around it, therefore, if you put chocolate in the fridge or freezer it doesn't melt, but if you hold it in your hand of put it in the microwave, it does.
What temperature is beryllium kept at?
Beryllium is kept at relatively low temperatures, because it is a metal with a low melting point. It melts in your hands.
Why is tin in solder?
Because it melts at a realtively low temperature, it doesn't corrode, and it has excellent conduction qualities.
What melts faster chocolate or cheese?
the chocolates melts more soon than the cheese...the reason s they have low temperature level
How many degrees must the temperature reach in order for chocolate to melt in the forest?
About 70 °C, you can reach the temp. by collecting energy from sun by mirrors.
What type of star has low mass low temperature and low absolute magnitube?
A red dwarf.
What prevents evaporation?
Keeping the molecule in a low temperature. The temperature varies on what type of molecule.

Why sodium is not use as conductor?
1) It melts at low temperature. 2) With oxygen and water it make reactions at normal temperature. 3) It burn at 883 degree Celsius so it is not use for high temprature.
What Type of star has a low temperature and a low luminosity?
Robert De Niro, the years of 2020+
