Warmer air rises, creating clouds and precipitation. Cooler air sinks, making it drier and clear... Which spot(s) in the diagram show areas of HIGH PRESSURE? * The DESERT areas (both 30° North and South)
The TROPICS area (at the equator)
Both the DESERT and TROPICS areas.
Neither the DESERT or TROPICS areas.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

The material that keeps its new shape after it is stretched is called?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
