Energy: the ability to do work. Work= force x displacement. Power=energy/time Power is measured in watts or horsepower. Joules/sec=watts 1hp=746w=1kw Basal metabolic rate 2000kcal/day= 100w Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole. Devices inbetween convert this energy to another form‚ Efficieny- e.motor=85%‚ combustion= 20% Hydrogen is not a source of energy but a means of transportation Types of energy:

During an experiment‚ there was a glass eye dropper placed into a bottle filled to the brim with water with the cap closed. The glass eye dropper floated in the bottle when the bottle was left alone. When the bottle was squeezed‚ however‚ the glass dropper sunk to the bottom. When the pressure was released from the bottle‚ the dropper floated back to the top of the bottle. The dropper floated at the top of the bottle when no pressure was applied‚ because the air inside the dropper was less dense

Combustion of Alkanols Aim: To determine which alkanols has higher heat combustion Hypothesis: The alkanols with the longer carbon chain will a higher heat combustion Background Information: Heat combustion can be calculated by using various formulas. By using ΔH= -mcΔT‚ we can gather the amount of heat released. Since the experiment is exothermic‚ ΔH will have a negative value. By dividing the total amount by 1000‚ the units changes into KJ. Divide the total KJ of heat by the amount of fuel

PHY 114: Absorption of Nuclear Radiation Abstract: The purpose of this experiment was to determine the mass thickness attenuation factor for beta rays when they pass through polyethylene sheets of varying thicknesses. This was done by using an apparatus that measured the seven different intensities and then taking these values‚ putting them through a number of calculations and finally generating a graph of ln(I_corr) versus the thickness of the polyethylene sheets. Once this graph

Heat release rate of a subway car on fire in a shrink-scale model Abstract: Heat release rate in a shrink-scale model of a subway car on fire is measured for various aspects of an ignition source and simulated materials differing in material by using shrink scale model. The time is required to reach the value‚ although the maximum Heat Release Rate value is independent of the position of the ignition source. The best method for determining the heat release rate is the maximum Heat Release Rate
