lab‚ we are now able to calculate the molar heat of combustion for paraffin‚ since we have the difference of the mass in candle before/after and the periodic table of elements (for converting g to moles of paraffin). Molar heat of combustion = (kJ of heat)/(mole of fuel) However‚ we do not know how much heat was released nor the mole of fuel (paraffin). In order to find the amount of heat released‚ we use the formula: g=mcΔT. Here‚ g represents the heat‚ m represents the mass of water‚ ΔT represents

Although the Era of Good Feelings is known as a time of remarkable growth and development in the United States‚ it has also been considered a time of "evolution in American nationalism." The years following the War of 1812 have been called the "era of good feelings" because the period was one of one-party politics ted by the Jeffersonians. In the Election of 1816‚ James Monroe defeated the last of the Federalist candidates and caused a decline in the Federalist Party. During this time‚ there

situation for thick pipes is‚ however‚ more complex. [pic] The figure shown above represents the condition in a thick walled pipe. The area for heat flow is proportional to the radius – as may be seen‚ the area at the outside wall of the pipe is much greater than the middle. As a result the temperature gradient is inversely proportional to the radius. The heat flow ‘per unit length of pipe’ at any radius r‚ is [pic] cf.
