Will all solids melt if heated to a high enough temperature?

Question

For a chem homework question;
"Criticize the statemen 'all solids will melt if heated to a high enough temperature.'"

Answer 1

The statement is not true.
Some solids will melt, some will undergo sublimation, some will decompose.

Answer 2

Most complicated organic molecules will decompose before they get hot enough to melt. For instance you can't melt proteins. Some substances like CO2, carbon and iodine sublimate, that is, go straight from solid to gas without melting at atmosphericpressure, but you can liquefy them under high pressure. But apart from these exceptions, yes, all solids melt if they're hot enough.

Answer 3

Most solids will melt at their melting point. However, some solids sublime, turn directly from a solid to a gas. Others will decompose, some burst into flame.

Answer 4

All Solids

Answer 5

Yes all solids will liquify, the problem is sometimes the point of combustion is lower than the point at which it turns to a liquid. Also if its head together by anything else, like water, the water will boil out before it reaches liquid point and thus it will fall apart, if you contenue it will either catch fire or turn to a liquid.
