State what can be inferred from the temperature difference between two objects.
State the fundamental principle used when measuring temperature.
Using your response to part (a)(ii), explain why two thermometers might not show the same temperature for an object.
An aluminium block with mass $670\ \text{g}$ is heated at a constant power of $95\ \text{W}$ for $6.0\ \text{minutes}$. The specific heat capacity of aluminium is $910\ \text{J kg}^{-1}\text{K}^{-1}$. Its initial temperature is $24\,^{\circ}\text{C}$. Assuming that no thermal energy is lost to the surroundings, show that the block ends up at $80\,^{\circ}\text{C}$.
Using the information in (i), plot on Fig. 1.1 a line that represents the block's temperature, assuming that no energy is lost to the surroundings.
Using Fig. 1.1, calculate the total energy transferred to the surroundings during the heating process.
