    Topic: Millikan Oil-Drop Experiment The Millikan Oil-Drop experiment was the first experiment to determine the charge of an electron. In 1909‚ Robert Millikan ultimately came up with a way to determine this charge through finding the minute electric charge on a droplet from an oil mist. Basically‚ Millikan started with an enclosed chamber that had two flat plates inside‚ one with a positive charge and one with a negative charge. The portion is split up by the positively charged plate so at the beginning

    NS 10.5 (pg 1 of 2) Heating and Cooling Curves What happens when we heat a sample of ice that is initially at -15°C? The addition of heat causes the temperature of the ice to increase. As long as the temperature is below 0°C‚ the sample remains frozen. When the temperature reaches 0°C (the melting point of water)‚ the ice begins to melt. Because melting is an endothermic process‚ the heat we add at 0°C is used to convert ice to water and the temperature remains constant until all the ice
