A metal spoon is placed in a bowl of hot soup. Explain how thermal energy is conducted through the metal of the spoon.
Define, in words, specific heat capacity.
A student heats a metal specimen to 80 ∘C80\ ^\circ\text{C}80 ∘C. The student then places the metal specimen in an insulated cup containing 100 g100\text{ g}100 g of water at 18 ∘C18\ ^\circ\text{C}18 ∘C. The final steady temperature of the water and the metal specimen is 24 ∘C24\ ^\circ\text{C}24 ∘C.
The specific heat capacity of water is 4.2 J/(g ∘C)4.2\text{ J}/(\text{g}\ ^\circ\text{C})4.2 J/(g ∘C). The mass of the metal specimen is 120 g120\text{ g}120 g.
Calculate the specific heat capacity of the metal.
