Q1. A 0.38 kg iron horseshoe that is initially at 580°C is dropped into a bucket containing 21.8kg of water at 21 °C. What is the final equilibrium temperature (in °C)? Avoid any heat transfer to or from the surroundings. Do not enter units.
Q2. Assume you were the first to measure the value of some physical constant experimentally. How would you provide an estimate of experimental uncertainty?
