Another question.

 

Can a mixture have a different melting point from its constituent elements?

 

 

 

thanks in advance

yes. alloys in particular. also if you mix finely powdered organic compounds you get melting point depression. as a lab experiment this sucks but can be used to analyse purity.

Yep.

 

An example is that tin has a melting point of 231.93 °C but when in mixed in a specific ratio with gallium (melts at 29.76 °C) and indium (melts at 156.6 °C) the compound has a melting point of about -20 °C.
