The U.S. was thrown into recession only a few months after Reagan took office in the 1980s, and the Great Recession had already begun by the time Obama entered the White House in 2009. Andrew Soergel and Ethan Rosenberg for USN&WR; Source: Bureau of Economic Analysis.
Temperature affects the speed of fermentation. Between 60Â°F and 65Â°F, it will take 6 weeks to make sauerkraut. The ideal temperature is between 70Â°F and 75Â°F where it will ferment properly in 3 to 4 weeks.
Best Answer: Specific Heat is the energy required to raise EACH gram of a material by 1C. This is expressed in J/gC. The temperature change is 82.1C - 30.7C = 51.4C. The Aluminum weighs, not 1g, but 625g. m x c x Î´T = Q 29.5g x 0.45J/g/Â°C x (40 - 25Â°C) Î´T = 199.125 Joules (= 0.199kJ) of heat absorbed. (you can say 0.200kJ) If 8.4kJ was used as in your initial statement, to raise the temp. by 5Â°C, the mass of iron must have been much greater than 29.5g. or, 8.4kJ is an error. 29.5 x 0.45 x 5 = 66.4 kJ.
