Energy is added to the liquid by the immersion heater - the metal coil placed in the liquid after the thermometer reading stabilizes. The immersion heater delivers energy to the liquid at a rate of 21.1 watts, or 21.1 joules/s. Notice that there i a stopwatch available when you click the tool icon in the upper right. Hint: Energy delivered = rate x time

FI Part 2: Analyzing the differences between experimental and published values You may have noticed that in spite of carefully measuring and calculating, the values for the specific heat you determined experimentally do not match the published values for those concentrations of propylene glycol solutions. Let's explore why. N 1. What are the potential sources of error in this experiment based upon your results? Apply CER to your answer. Hint: Consider whether your results are higher or lower than expected. Explain how this could happen. 2 C: Claim answers the question E: Evidence provides a numerical/quantitative discussion to support the claim R: Reasoning explains why your the evidence supports the claim using theory.
