Four spoons wooden metal rubber and plastic were placed in boiling water with candle wax on them which one did the melt from first?

The metal spoon will melt the candle wax first. Metal is a good conductor of heat, meaning that it can transfer heat quickly from the boiling water to the candle wax. The other spoons are not as good conductors of heat, so they will take longer to melt the candle wax.
