Flash points are determined experimentally by heating the liquid in a container and then introducing a small flame just above the liquid surface. The temperature at which there is a flash/ignition is recorded as the flash point. Two general methods are called closed-cup and open-cup. The closed-cup method prevents vapors from escaping and therefore usually results in a flash point that is a few degrees lower than in an open cup.
There are two methods for roasting a whole chicken: Regular method: 1  Preheat oven to 350 degrees F (175 degrees C). 2  Roast whole (thawed) chickens for 20 minutes per pound, plus an additional 15 minutes.
How long should a chicken be baked in the oven? The amount of time needed to bake a whole chicken depends on the temperature of the oven and the size of the chicken. For example, at 375 degrees Fahrenheit, a 3-pound chicken takes 1 to 1 1/4 hours to cook.
