What does the term 'Hot' refer to in the context of thermal energy?

• Having low thermal energy

• Having high thermal energy or lots of particle motion

• A material that does not easily allow heat to pass through

• A measure of the average particle motion in a substance.

A wooden spoon and metal spoon were placed into a mug of hot tea at the same time. Upon being touched, the metal spoon felt hot in comparison to the wooden spoon. Which of the following statements best explains why?

• The tea was hotter in the region where the metal spoon was placed.

• The tea was hotter in the region where the wooden spoon was placed.

• Wood is an insulator and prevents the transfer of thermal energy from the hot tea to your hand.

• The wooden spoon lost thermal energy to the tea in the mug.
