Fig. 4.1 presents the apparatus used to determine the specific heat capacity of a metal.
The electric heater is turned on and delivers 17000 J of thermal energy (heat) to the metal block. Its temperature increases from $16\,^{\circ}\text{C}$ to $38\,^{\circ}\text{C}$. The block has a mass of 850 g. No energy is lost from the metal.
(a)[2]
Calculate the specific heat capacity of the metal.
(b)[1]
Calculate the heat capacity of the block of metal.
(c)[1]
Explain how thermal energy (heat) is conducted through the metal.
Worked solution & mark scheme
This 4-mark question has a full step-by-step worked solution and mark scheme. One marking point: “Thus, $c = E / (mT) = 17000 / (22 \times 850)$” …
