An engineer carries out an experiment to determine the specific heat capacity of a copper crucible.
The engineer measures the temperature of the crucible using a digital temperature probe. The probe's screen displays readings to one decimal place, such as 24.3∘C24.3^\circ\text{C}24.3∘C. What is the resolution of this temperature probe?
To minimise thermal energy transfers to the surroundings, the copper crucible is encased in a ceramic insulating jacket. The combined mass of the crucible and the insulating jacket is measured to be 2.45 kg2.45\text{ kg}2.45 kg. The mass of the copper crucible alone is 1.85 kg1.85\text{ kg}1.85 kg. Calculate the mass of the insulating jacket.
During a heating test:
Calculate the specific heat capacity of copper from these experimental results. Choose and state the correct unit from the following options: J/kg\text{J/kg}J/kg, J/kg∘C\text{J/kg}^\circ\text{C}J/kg∘C, or J/∘C\text{J/}^\circ\text{C}J/∘C.
