Heat transfer, Conservation of Energy question: Students A and B used the following steps to find the heat capacity of a sample of duraluminalloy:1. Filled a polystyrene cup with approx. 125 g of water at temp 55°C2. Observed the temperature of the hot water at 1 minute intervals for 8 minutes3. Took duralumin metal sample from constant temperature vessel at approx. 20°C and submergedit in the hot water4. Observed the temperature of the water plus duralumin at 1 minute intervals for 8 more minutes See the image below for the results. 1. in what ways was heat energy transferred in this experiment? Is it the hot water transfer heat to the alloy sample and the environment of something else? 2. Should the data point at t=+0.5 minutes be included in the line of best fit for positive time? 3. What were the temperature changes of the water and the alloy sample, estimate the uncertainties? 4. Find the specfic heat capacity of the duralumin alloy sample. Estimate the uncertainty in this…
