My project is how fast does heat attract to different materials? The purpose
of this project is to inspect which type of material conducts more heat. Four different
materials will be put to the test: metal(aluminum), wood, glass, and plastic. For this experiment the metal, wood, glass, and plastic should be cut to the same size. Second, the four materials must go in the refrigerator for 30 minutes. Third, take the materials out of the refrigerator and place them under a 60 watt lamp. Fourth, record the temperature right away. To do this, place a thermometer under the material and record its temperature and do the same on the other materials. This should continue for 10, 20,….60 minutes. To conclude, take the data and of the experiment and put together a graph. The results of the experiment state that glass heated up faster than metal, wood, and plastic. All the materials started just about the same temperature. After 10 minutes
every one of the four materials was at the same temperature. After 20 minutes glass
started to increase in temperature while metal, wood, and plastic stayed at the same
temperature. After 40 minutes glass increased in temperature of 31 degrees Celsius. In
60 minutes glass had the highest temperature of 33 degrees Celsius, and metal (aluminum)
had the lowest temperature of 27 degrees Celsius. My hypothesis was wrong metal (aluminum) did not get the highest temperature, but glass did. Glass had a temperature of 33 degrees Celsius and metal (aluminum) had a temperature of 27 degrees Celsius and that was the lowest temperature out of all the
materials. Since I was using aluminum which is another type of metal, but with air particles
inside it conducted less heat. Glass, plastic, and wood were all supposed to have the lowest temperature, but it turned out to have the highest temperature. Several questions from me occurred during my project. Since aluminum is a metal why didn’t it conduct heat the fastest? My experiment was done inside what would happen if I did my experiment outside? Would the temperatures stay the same or alter?

I have a Civil War paper I have to write and on the handout my professor wrote:
"Finally, be sure to mine my lectures in answering this questions."

He said that we don't need to cite his lectures. So, what does "mine my lectures" mean? Or is it just a simple typo...

i need help on a project that im doing for class. i have to make a 5 day menu with all 3 meals, based upon the following numbers: 1853 calories, 278 grams of protein, 566 grams of fat and 1019 grams of carbohydrates. THERE IS TO BE NO ALCOHOL! these numbers are daily and cannot be carried over to the next day. the calories can be +/- 100, but the others have to be near or a wee bit over their limits. im doing the best i can but its giving me a migraine.

the subject is a 29 y/o male with a moderate activity level weighing 170 pounds. i got 1853 by multiplying 170 by 10.9 then that number by 1.7. then i times that by 0.15 for the protein, 0.30 for fat and 0.55 for the carbs.

any help would be appreciated.
