Experiment B2‚ Heats of Combustion – The Bomb Calorimeter. Objectives: To calibrate a bomb calorimeter by the combustion of benzoic acid. Then to use the calibrated calorimeter to measure the heat of combustion of naphthalene and calculate the heat of formation of naphthalene. Theory: q = C.ΔTBA C = q / ΔTBA Moles = mass / Mr ΔŪ = ΔU / moles ΔHoc‚298 = ΔŪoc‚298 + PDV = ΔŪoc‚298 + RTΔn C10H8 (s) + 12O2 (g) 10CO2 (g) + 4H2O (l) ΔHoc‚298 = - 1

For the Giant drop ride if you wanted to find the final velocity you would multiply the acceleration of gravity‚ which is 9.81m/s/s‚ times the amount of time it took for you to fall. This equation is Vf(velocity final)=Vi(velocity initial)+a(acceleration)*t(time). Since the initial velocity of the drop is zero we don’t have to worry about adding that on. The final velocity comes out to be about 84 miles/hour. This equation says nothing about mass or weight meaning that the weight of the passengers
