Plzz plzzz i'll give you 25 pointshow does the water cycle influence weather in your area? use complete sentences and a specific example from your experience.

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.)

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
