The energy density in a pellet of algae is determined by a bomb calorimetry technique, in which the food is burned (in an oxygen rich environment) and the amount of heat transfer ismeasured. How many joules of energy per kilogram are there in dried algae if when burning a5.00 g algae pellet, and transferring this energy to 0.500 kg of water held in a 0.100 kg aluminumcup, a 54.9oC temperature increase is observed? The specific heat of water is 4186 J/(kg K) andthe specific heat of aluminum is 900 J/(kg K)

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
