3. Calculate the work done, W=mgh for a mass of 300 g. Then, using the accepted value for the specific heat of water, calculate the change in heat, Q=cm„AT for the same data point. a) Calculate the ratio W/Q. b) Suppose scale used to measure the mass of 300 g was not properly zeroed, and the mass was, in fact 350 g. Recalculate the ratio W/Q. c) Compare the ratios from part a) and b). Do you suspect the scale was zeroed properly, or not? Why? 3. Calculate the work done, W=mgh for a mass of 300 g.
