The Difference Between an Alloy and an Amalgam
Delicious77 [7]

Mixtures or combinations of various different metals or metallic substances form things called alloys. An alloy composed of mercury and other metal (or metals) forms "amalgam". When a true alloy is created, the component metals are combined together at a temperature which is greater than the melting point of all of them.

Also, it helps to remember the word "amalgamate", which means "to alloy (a metal) with mercury" according to Dictionary.com.


Hope this helped :)

Compare and contrast between nuclear fission and fusion
Drupady [299]

Both create energy. Both require atoms.

Fission is ripping the atoms apart, fusion is forcing them together. Fission takes less energy because it's easier to rip unstable atoms apart but pushing two atoms that have similar charges together is extremely hard. Fission is currently mainstream on earth, but fusion is known for taking place within stars.
