Based on your results, which fuel produces more energy per gram burned? Give an explanation for the difference. (Hint: Ethanol, C, H,OH, is an oxygenated molecule; paraffin, CH,», does not contain
oxygen.) Compare AH combustion of fuel values for both paraffin and ethanol. Ethanol burns hotter
than paraffin wax, but then why does paraffin produce more energy?

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
