All right, well, we're talking about phase transitions here:
when matters changes from one form to another,
usually due to an increase or decrease in heat.
Let's say we take our favorite drink,
pour it into a glass,
and add ice. Well, gently give it a stir,
and, ah... Cool and refreshing.
But then we have to take the dog for a walk, so we leave the drink and come back in an hour.
When we get back, well, we now have a gross
water-y drink. That's because the ice, which had been solid,
melted into water, therefore diluting down our drink.
So the best answer choice here is option C.
Melting is the process through which a solid becomes a liquid.
And just so we cover all the bases,
when a liquid becomes a gas, that process is called
evaporation. Think of boiling water turning into steam.
When a solid becomes a gas, that's called sublimation.
That's what happens when dry ice turns into fog.
Like, it goes from a solid to a gas without that water stage in between.
And when a gas becomes a liquid, that's called condensation,
like the water that forms on the outside of that once-cold glass.
And when we take chips, cheese, beans, and meat,
that's called nachos.
Don't mind if we do.
