Why do liquids have low melting point?

Although what the others have pointed out is absolutely correct and scientifically rigorous, I'll attempt to answer in terms of what OP might have meant, “Why do substances in the liquid state we see in daily life have such low melting points? read more

A water molecule does have a more complex structure than oxygen, though the R-410A (a mixture of two gases commonly used in heating pumps) is much more complex than water, and it boils at -48.5 degrees Celsius. read more

Melting Point/Freezing Point The terms melting point or freezing point are often interchanged depending on whether a substance is being heated or cooled. For liquids it is known as the freezing point and for solids it is called the melting point. read more
