Question

A wooden spoon, steel spoon, and a gold spoon are initially placed in a bowl of hot water. When taken out of the bowl, which spoon will be hotter for a longer time?

Answer 1

Answer:

The answer will be wooden spoon.

Answer 2

A wooden spoon will be hotter for a longer time out of a wooden spoon and a gold spoon when placed in hot water.

• Thermal Conductivity is a measure of the body's ability to transfer heat and is directly proportional the rate of heat transfer of the body.

• Wood is a poor conductor of heat i.e. it is an insulator so it would hold up heat for a longer time.
• Gold spoon is a better thermal conductor than steel so it would take up more heat from the hot water and lose it more quickly to the environment.
