Eutectic system

Imagine you have a popsicle that has two flavors, strawberry and banana. If you like both flavors, you might want to lick the popsicle equally on both sides until they are both gone. But what if you like strawberry more and you want to finish it first? You would have to eat the strawberry flavor faster and leave the banana part for later.

Now let's imagine this situation for a mixture of two metals. Some metals melt at a lower temperature than others. In this case, we call the low-temperature melting metal "X" and the high-temperature melting metal "Y". Just like the popsicle, if both metals are mixed together and heated up, they will eventually melt and form a liquid mixture.

But, what if there is a specific temperature at which the mixture of X and Y melts together as one substance, instead of being a mixture of two separate liquids? This is called the eutectic temperature. At this temperature, the mixture of X and Y behaves like a single liquid, just like when the strawberry and banana flavors of the popsicle melt and mix together evenly.

So, in summary, a eutectic system is when two metals can mix together to form a single liquid at a specific temperature, like strawberry and banana flavors melting together in a popsicle.
