Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises

Suzana Milic Thomas Edison V. Nikola Tesla 26 March 2013 Nikola Tesla was born on 10 July 1856‚ in Smiljan‚ now Croatia. He was the son of an Orthodox priest. In history‚ he will be remembered as a scientist who is openly opposed to the then unquestioned scientific authority to Thomas Edison. Tesla insisted on converting DC into AC‚ which even the great scientist Edison‚ did not have in his head. At the very beginning‚ Edison was Tesla’s idol and worked with him for a time as an assistant. He

Using Fruits ( Lemon‚ Orange ) As Battery Purpose To demonstrate how an electrical current can be generated using citrus fruits (such as lemons or limes) that is strong enough to power a small light bulb. Additional information Batteries are devices that store chemical energy and convert it to electrical energy. Consisting of one or more voltaic cells‚ batteries come in various sizes and forms and are integrated into most electronic and portable devices. Electrical current is the flow
