From which knife did the butter melt off first?
Here's how kids have voted so far:
60% the metal knife
21% the plastic knife
18% they came off both knives at the same time
How's it work?
The warm water will transfer some of its heat to the knife handles. The handles will then transfer that energy to the blade, which will melt the butter. The process is called conduction. But some materials conduct heat faster than others. One of the two knives will transfer heat to the butter faster than the other. Want to find out which one conducts more quickly?
