Question 8 NECO • 2023 • PHYSICS • essay

A 150 g metal block is heated in a furnace to 200 °C and then quickly transferred into a well‑insulated calorimeter containing 500 g of water at 25 °C. After thermal equilibrium is reached, the temperature of the water‑metal system is 30 °C.

Question Parts

( a )

Assuming no heat is lost to the surroundings, calculate the specific heat capacity (c) of the metal in J g⁻¹ °C⁻¹.

( b )

If the metal were replaced by a 150 g piece of aluminium (c = 0.385 J g⁻¹ °C⁻¹) initially at 200 °C, determine the final equilibrium temperature of the system under the same insulated conditions.

( c )

Discuss two possible sources of error that could make the calculated specific heat capacity differ from the true value.
