If you touch a metal spoon and a wooden spoon that have both been in hot soup, which one will feel hotter and why?

• The metal spoon, because metal is a better conductor of heat.

• The wooden spoon, because wood is a better conductor of heat.

• Both will feel the same, because they are in the same soup.

• The wooden spoon, because it absorbs more heat.
