Adiesel engine accomplishes ignition without a spark plug by an adiabatic compression of air to a temperature above the ignition temperature of the diesel fuel, which is injected into the cylinderat the peak of the compression. suppose air is taken into the cylinder at 280 k and volume v1and is compressed adiabatically to 560 0cand volume v2. assuming that the air behaves as a n ideal gas whose ratio of cpto cvis 1.4, calculate the compression ratio v1/v2of the engine.

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
