Agas in a piston–cylinder assembly undergoes a process for which the relationship between pressure and volume is pv2 5 constant. the initial pressure is 1 bar, the initial volume is 0.1 m3, and the final pressure is 9 bar. determine (a) the final volume, in m3, and (b) the work for the process, in kj.

Part a)

Part b)

Explanation:

Part a)

As we know that the gas equation is given as

so here we know that

Now in order to find the final volume we have

Part b)

Work done in this process is given as

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
