Thermodynamics is the branch of physics concerned with the conversion of different energy forms.
•DeltaG (rxn) = DeltaG (pdts) - DeltaDG (rcts) •DeltaG°(rxn) = -R T ln K •
Temperature measures how fast molecules are moving or in scientific terms it measures the AVERAGE KINETIC ENERGY in a system. Temperature measures how fast molecules are moving. :):)
Alloys are useful (if this is what the question is getting at) because mixing elements of the periodic table alters their colligative properties.
i.e. mixing two metals could change substance's melting point, allowing it to more easily resist high temperatures. Also, mixing metals can change the way they bind together, and create an altogether stronger material than you can find using any single metal alone.They can improve a metal's properties
All chemical bonds, including those found in network solids, derive from the electromagnetic force. Positively charged protons attract negatively charged electrons. Although atoms start off with an equal number of protons and electrons, and are therefore electrically neutral, the electrons rearrange themselves in ways that create attractions between atoms.
